    This may sound like an odd thing to want to do, but there is a reason.

    I have a new 250GB HDD. I want to put it in a PC, create a 100GB NTFS partition and install XP. Then, I want to take the HDD out of the PC, connect it to my MBP using a USB adaptor and create an HFS+ volume in the remaining 150GB. Is it possible to do this and will OS X re-write the MBR/Partition Table such that the disk will still function as a Windows boot disk?

    When formatting it initially would I be better to leave the 150GB as free space, or create a partition but not format it?

    Alternatively, I could use Win7-RC rather than XP as, I believe, Win7 can use GPT. Would this be a better choice as GPT is the system used by OS X?

    Seems like a lot of work and since Macs use a difference partition type (GUID), it will probably over write the MBR.

    Why not create the HFS+ in OSX (and install OSX if need be), and also leave some space open for the NTFS partition you wish to create.

    Yeah, that's what i'm worried about - although OS X knows about MBR as it can read Windows formatted disks attached via USB.

    Except that I need the NTFS partition to be a bootable Windows disk.

    Perhaps I should explain why I need to do this.

    I have about 4 hours of family video on an old analogue camcorder that I want to transfer to DVD using iMovie/iDVD. I bought the PC version of Roxio's Easy VHS to DVD as, here in the UK, it is half the price of the Mac version :mad: Since buying it I've found that it can only produce MPEG-4 files in iPhone resolution (320x240??) and iMovie can only use MPEG-2 if I purchase Apple's MPEG-2 decoder so the only format that can be produced by Easy VHS and read by iMovie is DV (AVI) but these are ~15GB per hour and I don't have 50-60GB on either a PC or my MBP.

    So, the idea is to use this spare disk to install XP, rip the video to the NTFS partition, attache the HDD to my Mac, create an HFS+ volume and copy the DV files to it. Yes, I know OS X can read NTFS, but iMovie copies or moves the files it uses so I need a writable FS. FAT32 would be no good as there is a filesize limit of 2GB (or is is 4GB? either way, not large enough).

    That's what I need to do so if you can suggest any other (preferably easier) way to do it I'd be grateful.
