i don't have secure boot option..

and i can't load directly

[oldfred]

If you are sure you do not have secure boot - It is only on new systems with Windows 8 pre-installed, then from Boot-Repair uncheck the secure boot tick and rerun the rename files. That should change names back to defaults.

Boot-Repair - Updated Jan 1, 2013 to not rename first time, but rename if first time Windows does not boot. Post 706 and 711
http://ubuntuforums.org/showthread.p...769482&page=71
Boot-Repair copied /EFI/ubuntu/grubx64.efi to /EFI/Boot/bootx64.efi (in case the BIOS is hard-coded to boot into /EFI/Boot/bootx64.efi or secure boot
signed GRUB file shimx64.efi.
I disabled secure boot, and unchecked it in boot-repair. It now bypasses Grub and goes straight in to Windows.

Done this,

now the errors are:

"error: no such device: 38D2-86AD.
error: file 'EFI/Boot/bkpbootx64.efi' not found."

PS: Mint still loads ok

[oldfred]

That is the correct partition. gpt partitions look ok, but you have the error on the protective MBR. gpt has a protective MBR which is just the first sector on the drive like standard MBR(msdos) partitioning. It exists only so old disk tools see the drive is fully partitioned with gpt.

Not sure if gdisk will update protective MBR or not.

sudo apt-get gdisk

run it and issue the w command to write partition table. Since it will see gpt part as ok, I am not sure it will update MBR.

Am I doing something wrong?

I hope you pressed q. As nothing in new gpt table looks correct. Did you use sda1 not sda. You have to use drive not a partition, and that may be entire error?

According to BootInfo gpt table looked ok, it was just the MBR table that had issues. And we definitely do not want MBR converted into a new incorrect gpt table.

What does parted and gparted say?

sudo parted /dev/sda unit s print

[SimonaZ]

Yeah, I did press Q.
I used /dev/sda1. (I'll try to use sda now.)

Parted looks ok, what does gdisk now say with sda?

Should I W now?

[oldfred]

Yes, since it seems to see it correctly. Not sure still if it will update protective MBR.
