Update: rEFIt Troubleshooting Page

I just found a page on rEFIt's official website specifically about "Error: Not found while loading legacy loader" errors. It doesn't say anything about the new Al MacBooks, but it dates from 2006, so that's not the point. The point is this problem has appeared in previous Macs and apparently, it's resurfaced. Insert expletives or self-encouragement here (not that they're mutually exclusive).

I believe the problem that you encountered with having rEFIt automatically enabled is that your mac doesn't have time to recognize cd/usb drives before it boots up. Someone on the bug reporting part of refits site had a similar problem when he was trying to boot up from his super drive.

I tried booting into refit with option-key at start up but usb still wont show up.
 
Can't help you there, then. Just to make sure, you do know to copy the files and folders in the downloaded .iso or .dmg to the USB drive, not the .iso or .dmg file itself, right? And you know to copy the files and folders to the root directory of the drive, right?

I tried booting with the same USB drive using a white MacBook and while rEFIt didn't return any errors, I got a "Remove disk or other media" error. According to my research, this suggests that the BIOS was correctly launched when it realized I was booting a "legacy" OS (as in doesn't support EFI) from the USB drive, but because of some missing files on the drive it still wouldn't boot. This is in contrast to the new MacBook which apparently won't even launch the BIOS. I'll reformat and recopy all the files to the drive and try again later.

Must use Diskpart in Windows

@Kinkster:

Did you format with Disk Utility and copy the files with Finder in Mac OS X? Because that won't work. I just tried that and it doesn't show up in rEFIt. Then I used Disk Utility to reformat the USB drive as entirely free space, Boot Camp-ed over to Windows XP and used Diskpart to partition it, Windows Explorer to format it and xcopy to write all the necessary files.

I think the key is the Diskpart Active command, which sets the partition as bootable or something. There seems to be no equivalent in Mac OS X Disk Utility or Finder.

Note that the USB drive initially won't appear in Diskpart, try this excellent hack: http://www.lancelhoff.com/make-windows-see-any-usb-flash-drive-as-local-disk/

Also, the Windows XP version of Diskpart does not have a Format command, unlike the Vista version, so skip that line in the instructions in the first post. Instead, after partitioning, go to Windows Explorer, right-click the USB drive and use the Format... option to format it. Make sure to use FAT32 not NTFS.

I still get the same error in rEFIt on my Al MacBook and haven't retried booting the white MacBook, but this is one more piece of the puzzle.

ah that must be it. I did format in disk utility. I was thinking refit would show any device regardless of what was on it. ill try it with your advice tomorrow, already 4:30 heh.


You should make a little guide in a new thread. it would probably help quite a few people that won't find this slightly obscure thread.
 
I have managed to get Windows 7 (RC1 build 1700) running on my MacBook Pro (MacBookPro1,1). It'd like to say it was easy, but in truth it's taken me about 12 hours.

Reason: My CD/DVD will READ but not WRITE (burn).

The basic steps I went through:

  1. Install rEFIt
  2. Create USB install, as described by thefunkymunky
  3. Use Boot Camp Assistant (10.5.6, BCA 2.0) to repartition the internal drive
  4. Boot holding Option, select rEFIt option, boot Windows 7 installer
  5. Proceed through installer
  6. Install Boot Camp drivers (downloaded via Google, because we can't get them off the 10.5 disk)
  7. Installer drivers for graphics card (X1600) and airport via Windows Update

Now me bitching about why it took so long:

The first issue I had was with rEFIt. It didn't seem to activate itself, so I had to manually run /efi/refit/enable.sh. Easy enough to do, but I had to check the documentation for it.

Then I have some problems creating the USB installer. Formatting in Disk Utility (quick format I think), and copying the files across does not appear to create a bootable disk that rEFIt can use. I didn't have a proper Windows machine to go through the process described by thefunkymunky, but I did have a VM (VMware Fusion) with Vista. So, I mounted the USB stick directly to the VM, and created the disk. I can now boot into the installer using rEFIt.

It is at this point I realise, Windows doesn't let you install it to an external drive (in the way that OS X will quite happily allow you to). So, time to break out Boot Camp and make a partition on my internal drive. The first time around, Boot Camp Assistant tells me it can't move some files, and so can't finish the repartition. I've had this error before. When people first get a Mac, I tell them to create a partition, even if they aren't going to install Windows right away. Disks get themselves confused, and this breaks. Anyway, I tried fixing any errors using Disk Utility from the Leopard install DVD (running on an external firewire drive), but the same error happens. So, I backup and wipe the internal drive, reinstall OS X, then go back to trying to install Windows. It should be noted at the time of writing this, my Windows install is actually more configured than my OS X - ugh!

The installer is running, but at around 44% it complains some install files are missing or corrupt, and it can't continue. Great. So, I boot back into OS X, delete (but not format) all the files on the USB stick. Then I copy them using Finder from the mounted ISO in OS X. Reboot, and another go at installing Windows.

This time it gets all the way through the installer (including reboots where appropriate). It's not until the end it complains that drive C: is corrupt and unreadable. Thankfully these errors don't seem to have caused any real problem. The installer reboots, and next I'm looking at the Windows 7 first run screens.

Once I've got myself logged in, I install the 32-bit (for my lowly Core Duo) drivers from Boot Camp, as downloaded from the Interwebs. The main thing I notice working is audio! Still no graphics acceleration though.

I tried downloading the X1600 Vista 32-bit drivers from the ATI/AMD site, but they didn't seem to do anything. A quick Google, and I see someone asking the same question. Turns out you can download the right drivers (for both gfx and airport) via Windows Update (found in the Control Panel).

So now I have an install of Windows 7. Already they new task bar is creeping me out. This better be worth it.

Update: Things seem to be running fine, with one major exception: If I try to play any games, after a little while (5-20 minutes) the machine will suddenly shutdown, as if it's lost power. *poof* - gone. I don't know if this is a general problem with Win7, or if it's Mac-specific. Either way, it makes it pretty useless to me. :(

Update #2: Installed Vista with similar method, and have the same problem. I don't get this in OS X, so I guess it's an issue with Windows. I don't know if I can be bothered to install XP to test that.
 
I'm on a C2D MacBook2,1 on Leopard (MB21.00A5.B07, 1.17f0, rEFIt 0.13)

I tried everything as described by the previous posters, but I get the same error as Ldoh:

Starting legacy loader
Using load option 'USB'
Error: Not Found returned from legacy loader
Error: Not Found returned from LocateDevicePath
Error: Not Found returned from LocateDevicePath

The firmware refused to boot from the selected volume. Note that external
hard drives are not well-supported by Apple's firmware for legacy OS booting.

It looks like it's possible to do this only on that particular model of MacBook Pro.
 
First of all, thanks to all that took some time to post in this thread and share their experiences. I am looking to install windows 7 from my USB drive since my optical drive is messed up and won't read properly.
I will try this sometime during the week and post results here.
 
I'm just trying to install windows 7 from the USB drive.

I created the USB boot disk following the instructions, then copied the contents from the ISO to the USB using winrar (extract to), is this ok?
Then I turn on my MBP (not aluminium) with the USB and press the option key, I get the RefIt disk and press enter, then 3 options, boot MAC OS, boot MAC OS from HD and the far right says: Boot Windows From ____ and there is nothing after from, I don't know if this is how it's supposed to look, if it should say boot from USB. Anyways, I select this option, then it goes black and that's when I get: not bootable device, insert disk and press any key

And that's how far I am, up to that message. I followed the guide to create the USB boot, so I'll do it again using a Vista machine (same one I used before) and see if that helps out.
Any tips?
 
same problem over and over again creating the bootable USB from Vista, using the same USB flash drive and another one of also 4gb capacity....
any ideas?

Is there a way to extract the DVD image to a new bootcamp partition and boot from there and have it install it in that drive?
 
All that to save ONE dollar? wow.


Well when you say it like that...

Really though, I just don't want to re-burn new Windows 7 builds. Plus it'll make me feel like I'm putting this spare 4GB flash drive to use. But yeah, a 100 pack of DVDs are only like $20-$30. It's more about the technological hurdle/challenge to actually do it.

Also thanks for the info in the thread guys. :) Been looking for something like this for a while.
 
I'm stll having problems with it. I can create the bootable flash drive using a Vista machine, then I reboot and connect it, refit sees it and it appears in the boot manu, I select it and then it tells me that the device is not bootable.

But we're pretty certain it's the EFI that's to blame for this, right? Or is it simply a boot option issue?

I originally had tried using this guide but came up empty.

I thik it's a boot option issue. I mean, the thumb drive is properly formatted since it acts like a bootable disk in other machines, and my mbp sees it accordingly, it's just that the next step comes up empty.
I have an early 2008 mbo by the way.

Can I use daemon or other tool under XP to mount the image and install into that same partition XP is on? (this would be in another mbp, not mine)
 
update:
I think the problem is that my flash drive is just not bootable, even though rEFIt sees it when accessing the options, every time I stick it into another computer it still treats it like a flash drive, so that might be it. I'm calling it quits on this one. Cheers to those that got it working.

edit:
would just mounting the image from inside XP or Vista and then proceed with the installation work? I thought that it wouldn't because of reboots and all of that, but some say that windows 7 just copies the necessary files to the hard drive before the 1st reboot, then goes to work on the installation... again, this is not for my computer but a friend's mbp.
 
hmm this guide mentions ntsf and we're doing fat32 here, however some members have been successful with fat32

I kept running into the problem when entering:

bootsect /nt60 F: (F being the flash drive)

I get the message:

Target volumes will be updated with BOOTMGR compatible bootcode.

Could not map drive partitions to the associated volume device objects: Access is denied.

Mind you I was trying this within Windows 7.

yeah I got the same thing when I tried that using Vista.

And this is new, apparently my USB flash drive is bootable,my friend used it to install Win 7 on his mbp, no problems at all, so now I know it's my computer that's preventing me from installing. He formatted my usb, so I might stil be doing something wrong although I'm following the guide to the letter.
 
Add me to the list who've tried with a USB flash drive but get stuck with the error from rEFIt about newer Mac hardware - I tried on a Rev A MBA.

I know what follows uses a SuperDrive but someone ma find it ueful:

After the USB boot drive didn't work, I used my MacBook's Superdrive. Did a clean install of 7100 then shutdown immediately - no installing any updates, no activating or anything else.

Rebooted into OSX, deleted pagefile and hibernating file (which saved around 5GB) and used WinClone to shrink the partition down to 5GB.

Imaged this (again using WinClone) to an external USB hard drive, plugged it into the Air which had already ran BootCamp assistant prepare a partition.

Fired up WinClone again, restore from the 5GB clean install of 7100 and all was fine (after one check of the disk by Windows on first boot at least).

Copied BootCamp drivers to pen drive for the Air and went from there.

I'm wondering if mounting the image to a flash drive using a non-Mac machine (i.e., a Dell, home-built comp, etc.) and then trying to use it on my MBP would yield positive results?

up to this point, in all my tries, I've never used my mbp to mount the image to the flash drive and it hasn't worked for me yet. I don't have anything on my mac except mac os X.
 
using this guide:
http://www.intowindows.com/how-to-install-windows-7vista-from-usb-drive-detailed-100-working-guide

I was able to get rEFIt and windows in other machines, to see my flash drive as bootable... now, using another guy's mbp -Currently he has XP installed- rEFIt gave two options, boot windows from partition1 and from partition 3, I chose 1 and it booted into XP, next time around I chose 3 and booted into XP. I don't know if that's because he has Xp already installed, or because this was NTSF instead of FAT32 (I don't even know if it would make a difference), but that's where I'm at right now.
