(SOLVED) I can't find mem test on Grub menu

[linuxist]

This is an earlier post from my subject "Should I up-grade kernel"
Quote from djohnston:
"Open Synaptic. Look for memtest. Install memtest86+-4.20-1pclos2011 package. Once installed, you will have an extra item in the GRUB boot menu at the bottom of the list. Select the memtest item from the GRUB menu to run it. It will keep running until you choose to shut down or reboot the PC."
But...I can't see it.
Any advice please?

All I can suggest is that you manually edit the file

/boot/grub/menu.lst

to add an entry at the bottom for the memory test.


The entry should have the following form

title   Memory Test
kernel (DRIVE,Part)/boot/memtest

where you replace the (DRIVE,Part) with whatever is already used in the other boot entries.

If you wish confirmation please post the contents of the file

/boot/grub/menu.lst


Be aware that you need root privileges to even view the contents of this file.

HTH

Try this boot entry so ......  place it at the end of the file and ensure there is a blank line after it, and save the file.

title   Memory Test
kernel (hd0,0)/boot/memtest-4.20

EDIT .......  note the inclusion of the version number for memtest above. This is the version I have installed here, but should be the same for your installation. I omitted this on the original post 

[linuxist]

Yep! My installed version is the same.
I followed your instructions exactly & mem test is on grub list. When mem test is selected from grub list then it opens up ok.
Brilliant. Thanks so much. I'll mark this subject 'SOLVED'

Happy all is OK for you now ...  good luck with the testing of memory

It relies on a working CPU/north bridge as well as the RAM, so if you get no errors after several hours you know these are likely to be OK too, at least so far as connection to RAM goes. If you get failures at certain addresses these could be faulty. If it freezes at a certain point or you get random errors that could be any of these parts, or a dodgy PSU, which everything relies on.

Bearing in mind T6's opinion the machine is reaching the end of its useful life, I will be surprised if this runs for an extended period without problems, but you never know.
