Lemur Upgrade to 12.10 gone wrong or bad timing hardware failure

[isantop]

OK, so the Memtest off of the 12.10 is bad. I have gotten similar errors from the one I got from the lubuntu disk, version 4.20, I think. Is the version off the web site good?

Yes, though you'll want to write it to a CD, as it's difficult to put it on a USB drive.

Go into the Grub menu (by holding shift immediately after the System76 Splash screen), then make sure to choose a non-MemTest option. See if it will go into Ubuntu.

If MemTest it spitting errors, then it's likely failed RAM (Software can't cause RAM prblems), so i would open a ticket on our website: https://www.system76.com/my-account

OK, I received my memory a little while ago and finally have time to install and try to recover my machine.

1) how the *bleep* do I get at the memoryon a Lemur Ultrathin? I've taken out all the external screws, the battery, the HDD but something is still catching and preventing me from disassembling the thing (it seems to be caught somewhere near the middle of the mother board or toward the back).

2) assuming I successfully swap the memory how to I start the process of getting the OS upgrade completed if I don't have a Kernel to select in GRUB? I'm hoping I don't lose my home dir since I (stupidly) didn't finish backing up some data so I'm not real keen on doing a fresh install.

Thanks

quick update: figured out how to replace RAM (Damn you easy to remove keyboard!)

Currently running memtest 4.2 that I assume, based on this discussion, comes from ubuntu. I do not have a cdrom on my machine so..... suggestions?

I would borrow a USB CD drive. It's really the best way to ensure that you have a solid, good copy running.

memtest complete.... so is there a procedure I can go through to complete the upgrade and keep my /home dir? I do not see any kernel in the grub. only memtests.

If I do a fresh install of 12.10 is there some way to prevent an overwrite of /home

Can I run a live version, access the HDD /home data get if off and bring it back later?

finally, if I were to setup a /home partition (assuming I have to a fresh install) how much space would you recommend for the rest of the system on the HDD.

Here's hoping

To, perhaps, aid in more specific aid, I downloaded 12.10 and am running it as a livedisc. When I go to install, I get the notice that 12.10 is already installed. I have the option to install it again (along side the original) but the reinstall option is de-highlighted. On several other different threads I've read the following possible solutions:

1: select other (manual) and install on the same / partition without formatting and the original /home will be untouched but have to recreate my original user account names and passwords

2: use bootrepair to attempt to correct the grub not having the option of booting into 12.10

Which approach woud you suggest I choose if my primary concern is keeping and accessing my original /home directory.

Thanks

Fixed.

I decided to try the grub repair first since the initial install info displayed by the livedisc suggested the 12.10 upgrade appeared successful.

I followed the instructions from the url below, selected the recommended options and things appear to be correct. Account info remains, nothing to reinstall or initialize.
