so here is my problem: On my Lenovo t430i I replaced CD-ROM drive with 128 SSD OCZ-SOLID3 and installed latest Linux Mint 18.1 64-bit on it.
Everything was working flawless but I wanted to make it dual boot and installed Win7 64-bit on primary 320GB drive.
Windows is booting all right but I've lost access to Linux partition. To solve this problem I've used boot-repair CD and booted it from USB key.
So far so good. I attempted to repair and chosen NO-RAID option, and then Recommended Repair. Was following the wizard and got to the "Please open a terminal and type [...]" which I did. But last command:
sudo chroot "/mnt/boot-sav/mapper/mint--vg-root" apt-get install -y --force-yes grub-efi-amd64-signed shim-signed linux-signed-generic
gave me following error:
The following packages have unmet dependencies: linux-signed-generic : Depends: linux-headers-generic (= 188.8.131.52.83) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
Here I pasted entire terminal output: https://pastebin.com/f46vTs4E
And here: http://paste.ubuntu.com/24582235/ boot-info output
I've tried everything I coud find on Google but nothing worked so far. I don't want to lose my Mint partition because I have some important data on it and it would be a real pain to retrive it manually. If there is something unclear in my description, please let me know and I'll try to provide more info.
