Linux Mint 18.3 fails to install on HP laptop

J Harp · 03-08-2019, 06:27 PM

Still with it, delayed by other obligations which came up. I have went through the efibootmgr -o routine several times, 0000 is always listed above 0002.

Doing some more hunting I found this. What is your 0pinion? I think I can enlist a better typist to do the commands. My main concern now is avoid making it totally unbootable.

Look at the links in post 126

J Harp · 03-08-2019, 09:16 PM

I'm sorry, I did read the first link in post 126, then tried the second link and got a 4004 not found error, still get it. I somehow got distracted and just plain forgot to try the fix in the first link. I'll get on it in the morning, no use trying now because I can;t stay awake.

Good Morning to All.

I have been through all the recently suggested fixes, and have got the same result. Running bcedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi shows success, but it restarts to windows.

Looks like I'll have to put the screenshots on next post.

Meant to ask would a bios update be advisable? I know it's risky.

Screenshots.

Forgot to say got error on the reversal command, went on and the third command as a precaution.

Try this from live mint

Code:

sudo mount /dev/sda1 /mnt
sudo mv /mnt/EFI/BOOT/BOOTX64.EFI  /mnt/EFI/BOOT/BOOTX64.EFI.bak
sudo cp /mnt/EFI/ubuntu/shimx64.efi  /mnt/EFI/BOOT/BOOTX64.EFI

Thunderstorms in area, I'll do that after they get past here. Got to get them unplugged now.

J Harp · 03-09-2019, 04:13 PM

Sending this before rebooting, just in case something isn't right.

J Harp · 03-09-2019, 08:19 PM

Something wasn't right I thought I had it, but I didn't. I think I may have messed it up by running the efibootmgr -o thing again which would probably have undone what I had just accomplished. I'm not absolutely sure I did that, and I don't have screenshots to prove whether I did or not. Anyway it restarted to windows and I can't get it to repeat the first result.

I have redone everything from post 126, and have done the commands from post 157 at 5 or 6 times, always getting no return after the first running of them. Tried them when booted to the usb stick, but couldn't get anywhere with that. Thunderbird would open but wouldn't do anything, coulldn't post screenshots.

I'm going to assume that I screwed up the uefi system. If I don't hear that I shouldn't, I'm going to do a clean install of widows, and start from scratch. After I get Mint going again I'll go through these recent steps again and if that don't work, it's bye bye windows.

why are you running efibootmgr? run the commands in post 157 just as you see them nothing more nothing less, post sceen shots if you need to make sure it is right before rebooting.

colorpurple21859 · 03-10-2019, 08:26 AM

the fourth image looks correct. You shouldn't have done the mv command a second time as it will overwrite you windows version of BOOTX64.EFI.bak with a grub version of BOOTX64.EFI.bak. Don't know why you got the error in the last imgae. post the output of

Code:

ls /mnt/EFI/ubuntu

and

Code:

ls /mnt/EFI/BOOT

.

J Harp · 03-10-2019, 09:19 AM

I'm not positive I did that, but it seems most likely, I assume I did something wrong, but I failed to notice that I needed a second screenshot of the return.
Are you asking me to run the commands in post 157 again? I ask because you said I shouldn't have run the mv command a second time.

Am I understanding correctly that after running the mv command in post 157, especially if successful, the efibootmgr command should never be run again at any time, not just before rebooting?

colorpurple21859 · 03-10-2019, 11:49 AM

No don't run the commands a second time

J Harp · 03-10-2019, 12:04 PM

OK, understand that. Any way to undo whatever I have messed up?
