I have my machine setup to dual boot Windows 7 and Ubuntu 12.04 via grub. However, after I did a Windows Update today, it went straight to grub rescue. I messed with "set root" a little, and tried to reboot again. It then got to grub and I was able to boot Windows normally. Then I tried to reboot again, and now, it doesn't even go to grub or grub rescue. It just continuously reboots.
I attempted to purge and re-install grub via boot-repair from live-USB, but nothing has changed. The following is the bootinfoscript:
I have a weak understanding of bootloaders, so any suggestions would be greatly appreciated! I have no idea which direction to investigate next.
Please help! I urgently need the laptop this week. Thank you in advance!
Extra history that may or may not help:
After I first set up the dual boot, I had problems going from Windows to Ubuntu, not the other way around though. When I would try to boot into Linux, I would get a:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
I would then hard restart, and grub would load again, and then I would be able to boot into linux normally. After several months, the same procedure would cause a different error. Instead of a Kernel panic, I got:
error: invalid arch independent ELF magic
Again, I would do a hard reset, and then I would be able to boot normally, so I ignored this problem for a while until now.
