everyone. After having installed Ubuntu on my desktop Windows 7 won't run. There's a menuentry in the GRUB called "Windows 7" but when i press it nothing happens - the GRUB's menu just reappears.

I have EFI installed on my Sony Vaio S15 instead of BIOS. Here is the log from BOOT-REPAIR: http://paste.ubuntu.com/8173314/

I would appreciate any help u can give me. Thanks in advance. Alexey.

Might be bug #1091464. (Grub cannot boot Windows 8 with secure boot on) Try turning off secure boot and see if it works.

  • If the boot info is correct then: SecureBoot disabled. (line 666)

Does the Windows Boot Manager option in the firmware still boot Windows? There are some bkp-prefixed files, that shouldn't exist in EFI/Microsoft, leading me to believe this is another case of boot-repair bringing more confusion to UEFI setups than necessary.

Backup the whole data on the partition, copy the bkp files back to where they should be (just remove the bkp prefix). Install a boot loader like rEFInd or gummiboot to EFI/BOOT/bootx64.efi and probably have a look at efibootmgr.

The boot-repair author doesn't care very much about how UEFI is intended to work. Which is infact harmful to users, but too many people are fine with that.
