first there option boot windows 7 in grub boot menu, when tried boot windows 7, went grub menu. did bootrec /fixboot , bootrec /fixmbr, after grub menu didn't show anymore, , no os booted.

fixed grub couple of commands. grub working again , can boot in ubuntu, still can't boot in windows. when try boot in windows, there black screen white exclamation mark on it, waited 10 minuted nothing happens.

sda hdd, , sdb ssd windows 7 , ubuntu on it. use hdd store music , photos , such. (so can't format hdd right now)

there seems stuff missing bootinfoscript output, of partitions of sdb, fstab , grub.cfg. there errors reported.

have 2 disks handy. have grub installed mbrs of both disks.

think idea keep mbr code of disk windows on windows mbr code. way can boot windows if want without recourse grub or ubuntu. recommend reinstalling grub mbr on hdd (sda) , use boot normally, , restore standard mbr on ssd using windows can boot windows directly if need to.

boot ubuntu
run sudo fdisk -l , double check drive letters. identify hdd. i'll assume still sda - if not, use sdb here or whetever called:
sudo grub-install /dev/sda

reboot , tell bios boot hdd. check ubuntu boots ok.
reboot , use windows cd restore standard mbr ssd. reboot ssd , make sure windows boots.

reboot , set bios boot priority boot hdd first, , ssd second. or cd first, hdd , ssd if prefer.


should grub boot menu , choice of ubuntu or windows. if tell bios boot ssd should go straight windows.
