With Ubuntu 11 installed alongside windows 7, are there any known issues currently - while upgrading 7 to 8?

Even minor changes on 7 seemed to disturb the GRUB. Would it be wise to proceed?

Any possible precautions to be considered before upgrading?

Just disable Secure Boot – Ramhound Oct 29 '12 at 11:26
Installing Windows always overwrites the bootloader, so you have to be prepared to overwrite it back again. – pjc50 Oct 29 '12 at 11:31
Thanks pjc50, and is there no other way to bypass that? – JKarthik Oct 29 '12 at 11:35

Before you upgrade:

  1. Make sure that you a backup of all your important data.
  2. Make a bootable USB flash drive to install Windows 8.
  3. Make another bootable USB flash drive which you can use to boot into a live Linux distro and install the GRUB bootloader again if anything goes wrong.

Thanks Root, but I'm just reading other comments about Bootloader getting overwritten. Could you suggest anything to avoid that? – JKarthik Oct 29 '12 at 11:37
No Root, I'm not. – JKarthik Oct 29 '12 at 12:03
