Re: Mint thinks I have EFI BIOS; I don't -- Trouble; Help needed

Post by markfilipak »

Welcome to the movie. :D It's been running for a while. There are 2 things going on (and I think they're related):
1a, '/dev/sda1' is mounted here: /boot/efi,
1b, '/dev/sda2' is unclean, and
2, I can't fix them while mounted, but I can't make a live Mint USB stick with either 'mintstick' or 'unetbootin'.
From 'gparted':

Code: Select all

partition | fs      | mount     | size      | used      | unused    | flags
/dev/sda1 | fat32   | /boot/efi | 512.00MiB | 4.60MiB   | 507.40MiB | boot, esp
/dev/sda2 | ext2    | /boot     | 480.00MiB | 75.57MiB  | 421.43MiB |
/dev/sda3 | lvm2 pv | mint-vg   | 930.54GiB | 930.54GiB | 0.00B     |

Okay. May I ask how you know that?
Are you having problems booting into Mint or Windows?
The machine boots only Mint. I have WinXP in a VM, but that's not germane.
Or was there some kind of other problem that made you think that computer wasn't UEFI-based and that UEFI install of Mint was the wrong way to go?
Neither 'mintstick' nor 'unetbootin' will make a USB stick that's bootable. I can't remember my experiences installing Mint. That was quite a while ago. The problems only showed up lately, but there's no reason to believe that they weren't present at the git-go. Oh, an important point: The full file system check (that Mint runs on boot occasionally) has never completed. I've let it run for hours and no completion (and it's 'silent').
Did you in fact already install Mint?
Many moons ago.

Okay. May I ask how you know that?
Your parted --list output confirms that current Mint install is using an EFI System Partition (esp) on a GPT formatted disk. In other words, it's installed in UEFI mode which is only possible on computers with UEFI firmware. (Prior output you posted also confirmed this.) If you have a look at your fstab file you'll see an entry for the EFI System Partition there too.

Code: Select all

cat /etc/fstab
Don't know why you're having such a hard time getting live USB's to boot properly. Try a different brand of USB stick if you have one available. Sometimes, for whatever reason, one brand will work while another doesn't. Also, just to confirm how you're booting the USB: are you trying to boot by setting it as first boot option in the main UEFI/Bios settings menu, or are you invoking the per-session boot menu (using a different key-press than one used to access main settings) to get USB boot choice? The per-session boot menu is best option to use and should show both a UEFI and non-UEFI choice for booting the USB.

Worst case, if you have a dvd player, make a dvd instead -- that should work.

P.s.
Your UEFI/Bios is dated 10/27/2011, which is around the time UEFI firmware started to be used in place of old Bios firmware. So it's an early implementation of UEFI that may have some kinks that have been worked out in updated versions. If no method of creating a bootable USB works (and a different brand doesn't solve problem either), then you might want to consider updating the UEFI firmware. NOTE: Manufacturer will probably have any available update for it listed as a "Bios" update even though that is technically the wrong terminology to use.

Personally, since you were able to install already (presumably from live USB) before I don't think the firmware is the problem -- but who knows?

What if the Mint installer made an error? All the indications are based on what the Mint installer did. What if it screwed up?

It worked in Windows 7.
Also, just to confirm how you're booting the USB: are you trying to boot by setting it as first boot option in the main UEFI/Bios settings menu, or are you invoking the per-session boot menu (using a different key-press than one used to access main settings) to get USB boot choice?
I'm using F12 to bring up the boot option (per session... I can understand it) menu.
The per-session boot menu is best option to use and should show both a UEFI and non-UEFI choice for booting the USB.
There is no such option. There's no such option in the 'BIOS' either.
Worst case, if you have a dvd player, make a dvd instead -- that should work.
I could do that, but it wouldn't help my hard disk problems.

I checked the Lenovo website last Thursday. The 'latest' is dated in 2011, and I already have it. Lenovo support is non-existent.
Personally, since you were able to install already (presumably from live USB) before I don't think the firmware is the problem -- but who knows?
I did that with a USB stick that had been formatted and written in Windows 7. I still have that hard drive, and I could reinstall it and make the Mint install, but then there's the problem of explaining why '/dev/sda2' is getting corrupted -- unclean, and I can't simply ignore that. Then again, even if I manage to boot to a live Mint, I don't know what to do to fix the hard drive that's currently '/dev/sda'. I'm getting pretty fried. Got to go to bed. To be resumed tomorrow (later today).
