Cannot dual-boot Windows 7 and Ubuntu?
My set up is 1 PC 2 Disks disk1 ext4 ubuntu disk2 NTFS windows 7 and am wanting to dual boot with grub 2.
With grub I used to be able to set-up a menu item like this
title Windows 7 map (hd0) (hd1) map (hd1) (hd0) rootnoverify (hd0,0) chainloader +1
My install method was I installed win7 on disk 1 some time ago and to install ubuntu I cleared my 2nd drive and then disconnected drive 1 completely plugged drive 2 in as drive 1 and installed linux.
The logic behind the above grub entry was to keep both OS intact i.e. disconnect either drive and the remaining drives OS would/could boot because the windows boot loader remains in tack on disk 2 and grub takes care of disk 1.
I understand I can add the above to the 40_custom in /etc/grub.d/ but am not sure if update-grub will still go of and attempt anything I do not intend
Any help or assistance would be appreciated as it stands I can boot both O/S via boot device selection form BIOS but in the old days with a gentoo install I was able to do so with grub.
