Lost Bootentry in BIOS

[rando]

Hello I had a crash during the update due to lack of space after having resolved the problem by deleting old snapshots on restart it is the bios which opens, impossible to access manjaro kde which is the only Os Installed on my PC.
The only way I found is by restoring a snapshot in the grub. but whoever chooses the punishment after restarting remains the same bios. What can I do to get out of this?

[HowTo] Recovering from an interrupted update/upgrade

Difficulty: ★★☆☆☆ So you couldn’t wait until the update process had completed and you went for the reset/power button, didn’t you? And now you’re getting the message that you don’t have a kernel installed. Well, you’re not the only one — we’re seeing it happen all the time. So, here’s how to fix it, you impatient n00b. If you don’t happen to have a recent Manjaro installer USB/DVD/CD handy, direct your browser to this wonderful page, download t…

I just finished Recovering from an interrupted update/upgrade which did not resolve my problem. another idea that would save me from a complete reinstallation

What did that look like?

It did involve chroot, didn’t it?

If you can successfully chroot, you are essentially in your system - and can diagnose and repair it.
Easily (I’d say …)

If there was a lack of space:
did you address it?

inxi -zv8
may help you and others further

It seemed best to give you an extra thread. To prevent clutter from the update-thread.

A few questions up front so as not to waste time:

• Please specify inxi -zv8 (collected when booting from Manjaro ISO (or timeshift))
• Is this a legacy system with BIOS-MBR or GPT-UEFI or mixed?

You mention a timeshift restore. Did you complete the restore according to the timeshift instructions in the system that was then running?

You have landed in the BIOS. Is there an entry for booting that matches Manjaro? Does it work? Have you marked it as the default in the BIOS and saved it?
