I used Bootcamp to install a Windows XP. Now I'd like to upgrade to Windows 7, that I already bought. Problem: The Partition is in FAT32 filesystem.... Can I modify it to NTFS without formatting it? Is there a way to boot on the Windows 7? I bought an "Upgrade Pro" from internet, with download link. Thanks for your help!

I guess you don't need to change the file system . just upgrade it windows 7 will be take care about file systems – joe Nov 2 '09 at 11:02
Actually Windows 7 is giving me a message that it can't install because the HDD is in FAT32. – waszkiewicz Nov 2 '09 at 13:28

Inside Windows, you can type convert /fs:ntfs from the command line and it'll convert to NTFS.

I tried it, but it can'T work on the system partition. I'll try again. – waszkiewicz Nov 2 '09 at 13:29
I haven't experienced that problem before in XP. It will prompt to reboot. Perhaps that's what you're speaking of? – user3463 Nov 2 '09 at 13:43
convert /fs:ntfs will work with XP, even on a bootcamp or virtual machine image... I've done it... I agree with Randolph... – Benjamin Schollnick Nov 2 '09 at 13:46
Ok, it did work that time, after the reboot! Thank you! – waszkiewicz Nov 2 '09 at 16:07
Glad I could help. Be aware that the allocation unit size by default will be 512 bytes, so you might notice a performance improvement by formatting and installing from scratch at a later stage. Enjoy Windows 7. – user3463 Nov 2 '09 at 16:10
