I am having Acer aspire 4755. I initially had windows7. But tried Ubuntu 12.04. It was working fine. But when I tried to install Windows 7, i got this grub error. I am sure, I must have screwed up the grub file. So when I tried to run a live USB, DVD of Ubuntu back again to install Ubuntu , I got this error: panic occurred, switching back to text console. I even can't install Windows 7 with its starter CD. Kindly help me to remove Ubuntu or remove Grub and get my windows 7 working. I know I have to get the grub working, but how.??

what you meant by ` I even can't install Windows 7 with its starter CD` . If you start the dvd, it would not start grub in your hard disk. Can you describe more of your steps?– Web-EAug 18, 2012 at 19:33

and when I use Ubuntu live cd or Usb, it gets me the error message : Panic occured, Switching back to text console; when I click anything related with install, or try, or even test. Even I tried to resolve grub using supergrub, but it doesn't work.– RohitAug 18, 2012 at 19:55

You can replace Grub with Windows 7 boot-loader, simply boot from Windows 7 installer and rewrite the mbr
from the console, or if you are lucky it automatically corrects it.

I am not getting the console(cmd pmt). When I use Windows 7 starter, it directly goes to windows loading files and than the logo pops up and thats it.. DVD stops reading. nothing happens– RohitAug 19, 2012 at 10:45

Can you please edit your answer and add how exactly the user will rewrite the
mbr
from the console?– PeachySep 15, 2012 at 10:24
