What happened
I tried to resize partitions using Acronis Disk Director 12 and it failed leaving me with unbootable PC. I have dual boot configuration with ArchLinux and Windows 7. I partially restored linux boot and cannot restore windows boot.
1) Why windows boot loader loads from UEFI BIOS and not from grub2?
I have UEFI motherboard Asus M5A97. From UEFI BIOS when I run Windows Boot Manager bootmgfw.efi from flash drive and it shows error:
Code:
Status: 0xc0000225
Info: The boot selection failed because a required device is inaccessible.
I'm guessing it has something to do with bad bcd file. So I'mm looking into it. But the problem is that grub2 cannot even reproduce this error.
When using grub2 in rescue mode I do:
Code:
set root=(hd1,gpt7)
chainloader (hd1,gpt7)/efi/Microsoft/Boot/bootmgfw.efi
And get error: Invalid root device. (hd1,gpt7) is my efi partition where archlinux and windows boot loader efi files reside. I know that file is there. It even shows "cannot find file" when location is wrong. Why it fails? Why it cannot do what UEFI BIOS does easily? I tried every other option for root device to no avail. Somehow I'm missing something crucial about chainloading process.
2)After successful grub-install and efibootmgr motherboard boot option "arch" loads me into black screen with blinking cursor.
Again I can load into grub2(rescue mode) from flash drive in UEFI BIOS shell using the image generated by grub-install but I cannot load into grub2 using newly created boot option. Boot option "arch" just gives me black screen with blinking cursor. Typing does not work, holding shift does not work - so it's not video problem. Why loading grubx64.efi image into UEFI BIOS option under linux can produce this problem?

What changes did you make? What partition structure did you have prior to the change? I don't use UEFI but from what I've seen, your blkid output for sda1 isn't right and I've never seen an EFI partition on a logical partition before. Were you previously able to boot from the EFI partition on sda7?
>What changes did you make?
I had all windows partitions on /dev/sda first. Because Windows needs to be first. I don't remember exactly what was where. But I needed to modify my fstab after resizing to correctly mount everything. EFI partition was likely moved on disk, renumbered to sda7. But previously it was also on some logical partition.
>blkid output for sda1 isn't right
What's wrong? UUID? It's windows boot partition.
I don't use LABEL so I'm not sure what impact that would have. The entry you posted in your initial post trying to boot windows is incorrect since the files are on sda7, the entry should be (hd0,gpt7). That is, if you are booting from the installed Arch. If you are using a Live CD or flash drive, it may see itself as sda and your original should have worked if you had only one hard drive. Grub2 counts drives from zero, partitions from one:
Quote:
set root=(hd1,gpt7)
chainloader (hd1,gpt7)/efi/Microsoft/Boot/bootmgfw.efi
You're using GPT so the sda7 would be irrelevant as I understand it. If you don't resolve this, you might try running the boot repair which you can put on a bootable disk. If you do this, select the option to Create BootInfo Summary to review and/or post here.
This produces the same behavior with black screen and blinking cursor. Now thinking something bad happened to my MB firmware or I need to perform some magical command in uefi shell to restore something.

Yes, grub.cfg contains menu entry for windows near the end.

I find it hard to believe you actually created a LABEL for sda1 below:
It's probably how blkid deals with russian language.

This looks pretty basic. I might give it a try though.
Grub2 is pretty smart about listing hdds and their file systems. So I can easily understand what fs and what files are on disks.
I will read more about bcfg utillity and try to experiment from UEFI BIOS. Maybe there is a problem when setting efi boot option from linux and not from uefi shell. Will tell you guys how it went.
Solved this. The problem was either with partition table on disk sda or with incorrect partition order.
Fixed GPT table and partition order using fdisk and motherboard loads it, grub loads it.
