I have a laptop that had a dual-boot of Windows 7 and Ubuntu, with Ubuntu being the main booting OS (I could select the operating system to run at boot with grub). I recently deleted the Ubuntu partition thinking that would clear my installation entirely, but it didn't. Now, when I boot up my laptop, after showing the BIOs screen, the computer displays the "grub rescue>" prompt. I attempted to boot Windows 7 from the prompt, but it gave me an "Unknown command" when I tried to use the "boot" command.
My laptop has two partitions on the ~300 GB hard drive:
- "F: System Protected" - 100 MB, contains a BOOT folder and "System Information" folder, something like that
- "C:" - 86 GB, my Windows 7 partition
The rest of the space on my hard drive is free space. One of the biggest mysteries of this whole conundrum is where the grub is actually located
After a little Googling, I found Super Grub Disk, and tried multiple techniques to get Windows to boot up:
- "!WIN!" - Selecting this option only led me back to the main menu of UNetbootin
- "WIN => MBR & !WIN!" - Selecting this option displayed two lines of what appeared to be grub commands, and then my laptop shut itself off and rebooted
- "Language & HELP -> English Super Grub Disk -> Windows -> Fix Boot of Windows -> Syslinux -> hd1 86GB" Selecting this option displayed about 9 lines of commands/code (set out_device=(hd1)... set out_hd=hd1... back... dd (fd0)/boot/sgd/brs...), but did nothing more
I'm not sure what else I can do.
