I had Linux Mint previously installed.
Then I installed Manjaro Lysia. After the installation was concluded (no problems), I rebooted, but the following message appeared:
error: no such partition.
Entering rescue mode…
I have to cold boot the machine.
I’ve tried to reinstall from the USB key, but the same message appeared.
When I go to the BIOS and select Mint in the boot order, Mint will function perfectly (I kept dual booting).
The problem is with Manjaro.
I tried to redo the live USB, but it didn’t work.
p.s.: I’m not some IT professional, just a regular user, Linux enthusiastic, but I performed Ubuntu and Mint installation by my own, as well as some minor troubleshooting.
Lysia is already old. There was Kyria after that, and right now we’re on Mikah, and you’re bound to run into upgrade problems once you get Lysia up and running, because a lot has changed in the meantime.
Packages are now compressed with zstd instead of xz, and there have also been other major changes that could cause you to run into difficulties. For instance, GRUB was patched against the infamous Boot Hole vulnerability ─ which requires you to reinstall GRUB to the MBR or EFI system partition, depending on your setup ─ and now there has just been a serious upgrade to the PAM security system, which also brings its own set of problems to the table for certain users.
But that all said, your problem appears to be that GRUB cannot find the root filesystem. There could be multiple reasons for that, depending on what machine you’re on, how many drives there are, what partition table you’ve got, and so on. And ─ no offense, but I just have to say this ─ like most newbies to this forum, you seem to be under the impression that we have a crystal ball. I wish we did, but no, we don’t.
Best advice I can give you right now ─ and then I’m not getting into all of the difficulties I’ve mentioned higher up regarding the fact that your install .iso is outdated ─ is to boot up from the USB key in live mode and check the UUID of your root partition, and then compare that to what GRUB expects.
You can use the manjaro-chroot tool on the live medium to autodetect your Manjaro root filesystem, and then chroot into it, so that you can more easily edit /etc/default/grub with the correct UUID for your root filesystem ─ as well as /etc/fstab ─ and then run update-grub against the correct GRUB installation, because if you also have Mint on that system, then that will have its own GRUB, and you don’t want to update that one.
I’m afraid that’s as much as I can tell you with the scant information you’ve provided us with.
Thank you for your answer.
I do know there’s no crystal ball, specially when you’re not in front of the machine, just dealing with the given information.
I must correct myself: I installed version 20.0.3 (downloaded the iso yesterday from the site).
I tried to boot from a live USB before, but it displayed the same error message.
I even formatted and rebuilt the live USB, to be sure it wasn’t the issue
Thank you for your time though.
I’ll keep trying for a while.
If it doesn’t work now, I’ll give Manjaro another chance later.
I was in the Ubuntu system for a while. Now I’ve decided to expand on that.
obviously seem to be issue with usb. try to format it, then [install ventoy in the usb, then copy pase any iso or tools you need, check if ventoy boots and displays the list of iso you copied, just sharing my experience as we dont need to keep flashing with the new iso, just download and copy paste into ventoy. just felt to share this L I N K
I managed to finish the installation with a new iso.
I worked just fine, but when I turn off and turn on again, I get stuck in a log in page, where I type the password, type enter, but nothing happens (the forum doesn’t allow me to post links or pictures here).
