I have tried installing Arch Linux and what I ended up with was a partition scheme like this:
/dev/sda: /dev/sda1 NTFS partition (Windows 7) /dev/sda2 ext4 (Arch) /dev/sda3 swap
I don't know why, but for some reason I have been unable to mount the NTFS partition under Linux.
It's worth mentioning that the first partition is, for some reason, detected as an EFI partition and as on a GPT-formatted disk (my computer doesn't have an EFI bootloader and the drive has always had an MBR partition table).
I deleted the
sda3 using the Windows repair disk and was about to install a second Windows 7 installation alongside the first partition, but an error reported that the entire disk is a GPT drive!
The "Used" and "Free space available" sections indicate that the data on the first partition is still there, it's just that I cannot access the actual partition by any means. It seems that the first partition is with an MBR partition table on a GPT style disk.
How do I access the data on the partition?
