I recently installed Linux Mint on my computer but have decided I would prefer to have a dual boot system.

I wish to re-install my Windows 7 and create a dual boot afterwards but am having trouble i was hoping some of you guys could help me with

When I put in the Windows CD, the computer boots from the CD but then doesn't expand the windows files onto the disk

If I attempt to go to the BIOS, I get transferred to a black screen with a prompt for something called grub.

Can anyone help?

You've got to be sure that you have free space on your disk for the Microsoft's (yet) nonposix OS partition, then you can make a normal install and you lose your access to GNU/Linux. Finally you boot a GNU/Linux Live distribution and repair grub (that's a common tutorial).

  • Hi, I have tried this with both valid copies of windows XP and Windows 7. Windows 7 kicks me back to grub while windows XP suffers from the blue screen of death Does Linux mint change the way in which a hard drive stores data and this is the reason windows cant install or am i talking utter nonsense :)

  • That could be uncommon, but if you post relevant screenshots it sure can be worked around. If you have a nice cellphone maybe you can take the boot captures.

  • It appears i don't have enough points to post pictures. Hopefully my descriptions will suffice When the laptop boots normally it gets the error here Link. When i try to load it from Windows after deleting all partitions i get link but it never leaves zero percent on the expanding windows files setting

  • Getting error: unknown filesystem. grub rescue> shows you are failing to install Microsoft without damaging previous GNU/Linux installations. You solve this by installing Microsoft in separate partitions not used by GNU/Linux. Microsoft not expanding its files in the installation is something am sorry not be able to support.

  • Hi uprego. There is only a single partition on the PC. When you boot normally without any CD in the DVD drive it now immediately goes to the error: unknown filesystem. grub rescue>. Is the only way to fix this, to find a piece of software that can format the drive completely?
