I have been dual booting Win 7 and Linux for a while. Recently I updated to Win 8 Pro keeping Win 7. As a result, GRUB bootloader was replaced with Windows bootloader. So I couldn't get into Ubuntu.
I found this app it's called BOOTICE. I used it to change my MBR which replaced Windows NT 6.x to GRUB 2.0 hoping to get Ubuntu back working.
Now the PC won't boot. I get the following:
And I get a command line in which I can move around.Code:error: file not found grub rescue>
So the only USB drive I have is this 256MB drive. GParted Live is installed on it. I looked up my drive by booting on the GParted Live USB and my files/partitions are still there. Since the drive is 256MB, installing Boot-Repair or Ubuntu Live is no option.
So is there a way to fix the boot sector/MBR and write GRUB on it? GParted Live also has TestDisk but I don't know which type of MBR to choose, when both Windows and Linux are installed.
