system freezes and boot manager is reset on reboot

[adeswas]

Hi all. This is such a weird problem that I think it's a one off, but MAYBE someone out there has experienced it. Not even sure in which forum to post.

Have got an acer laptop with an aftermarket evo SSD. Dual boot Mint Tara (cinnamon) and Windose 10 with UEFI. Often while using Mint (doesn't happen with Windose), the system will crash--everything stops and I have to force a hard reboot. On that reboot I get an error that no bootable device is installed. I go to BIOS and see that the grub boot loader has been mysteriously moved from first boot option to 5th and windose boot loader is placed in number one spot. I put the grub bootloader back into the first boot option spot, save, reboot and all is well...until the next crash.

Happens too randomly to get an accurate fix on any process or event that triggers it. Have reinstalled Mint, and MS. No change. Has happened since Mint 18.1. All upgrades are up to date.

Any ideas. I'm no coder but have been around Linux for quite some time so I can make my way around the cli if need be

Thanks in advance
Adrian

It's hard to say from the description given. But a good place to start is to do this in a terminal and post the output so others will know what hardware is involved.

Code: Select all

inxi -Fxz

Another place to look would be the system logs found in /var/log and /var/crash see if anything shows up there.
I think the boot problem may be a separate issue. but not sure.

Thank you. I'll get on it
