No Bootable Device

[ITguy31]

I have been put incharge of all the Macs we are getting here at the university and they have purchased a MacBook Pro for me which is giving me trouble. We have installed parallels and that works fine but when you restart the computer it give a "No Bootable Device found. Insert Disk and press any key" error. If I restart it again holding the option key it gives me the option to boot into OSX but it will not boot into OSX normally anymore. How can I fix this?

I got that on my Mac mini also, I don't know the fix but I share your frustration. It's annoying. I don't even have a windows partition anymore either

It is frustrating. I wounder if it has something to do with bootcamp?

I think this is caused by the Windows install screwing up the primary partition. Windows set itself as primary when it is supposed to be Mac OS X. Terminal can be a pain if you are unfamiliar with unix command lines.

Before doing this try using diskutlity on your install dvd.

Setting Your Partition "Active" Using Fdisk

Words in bold below are things you must type (followed by Enter).

1. Boot your Mac OS X install dvd
2. Once the installer is running, go to the Utilities menu and open Terminal

3. Determine which disk your MacOSX partition is on

Type diskutil list

Verify which disk number holds your partition (disk0, disk1, etc.)
​

4. Start using Fdisk

Assuming the MacOSX disk is the first disk ("disk0"), then
type fdisk -e /dev/rdisk0 <== use "rdisk" with your disk number here !!

Ignore the error "fdisk: could not open MBR file ..."
​

5. Determine which partition for MacOSX needs to be set "Active"

Type p

Verify which partition is for MacOSX (1, 2, 3, etc.)
​

6. Set the partition "Active"

Assuming it is partition 1, then
type f 1 <== use your partition number here !!
​

7. Save and exit

Type write

Type y (yes you are sure)

Type exit (to quit)
​

8. Remove the install DVD and reboot
