Thread: Cannot boot into Win 7 after reinstalling GRUB: I get "Error 13" (details below)

my machine has 2 separate physical disks, 1 each os. windows (sda) , ubuntu linux (sdb). windows disk had "vista business x64" , linux disk has ubuntu 12.04. upgraded vista "win 7 pro x64" , expected, screwed mbr , grub not coming @ boot time. so, reinstall grub , go through whole 9 yards (booting live cd , mounting boot partition, reinstalling grub). please note installed grub on 'sdb' , changed boot sequence (in bios) pick 'sdb' first disk (because o/w grub not come up). did not install grub on 'sda' because afraid, might screw something.

can see grub come on boot menu options 'win 7' , 'ubuntu'. booting ubuntu ok when choose windows, error:

"error 13: invalid or unsupported executable format. press key continue.....".

when press key, takes me grub. below steps followed link (http://askubuntu.com/questions/88384...alling-windows). clues how can resurrect m/c?

another interesting noted chose boot 'ubuntu' grub, see message:

"boot (hd0,0) ext3, <uuid>"

wondering why booting (hd0,0) windows disk , not (hd0,1) linux disk (check menu.lst)???
