I can't install win xp and win 7 in the same disk - Page 2

post #11 of 13
The issue you have is between the MBR (XP install created) and the fact that you must have a GPT disk for an EFI system. XP can only use GPT disks for data.

A disk cannot be MBR and GPT at the same time, although i did read something once about GPT having a protective MBR

I know it is possible to boot windows 7 from a GPT partition on a BIOS based computer, as for dual booting this way......... I don't know. Sorry!

There is a Microsoft FAQ about MBRs and GPTs somewhere which might explain things better and help you out.

Bottom line is, i don't think it will be possible for the dual boot.

Through my own curiosity, i just looked into it, I found the FAQ page i mentioned:
http://msdn.microsoft.com/en-us/wind....aspx#MixMatch

Quote:
Q. What about mixing and matching GPT and MBR disks on the same system?

A. GPT and MBR disks can be mixed on systems that support GPT, as described earlier. However, you must be aware of the following restrictions:
Systems that support UEFI require that boot partition must reside on a GPT disk. Other hard disks can be either MBR or GPT.
Both MBR and GPT disks can be present in a single dynamic disk group. Volume sets can span both MBR and GPT disks.
