Booting to grub rescue

Just left windows 10 to go back to a linux OS after about 10 years not running one. I'm a bit rusty. And to make matters worse... I've broken something.

The basis of my problem is that when I try to boot, the first thing it says is that my sector size isn't big enough, "Error invalid sector size 65535" and after it spams that 3 times it switches to "No such cryptodisk found." Following that, it falls into grub rescue mode, and ...... here I am. I searched for someone with my issue, but it looks like nobody ever responded to his question, and it was closed on March 2nd.

I'm currently booted onto the actual pc (not from a Livecd, but I do have one ready)

What can I do to avail my situations?

Use the magnifying glass and sort by last post

Thanks for the speedy reply friend. I've been searching the forums for over an hour, and I have yet to find anything viable to fixing this problem. Each time I get involved with a solution, a new issue arises, and prevents me from moving forward. I appreciate the screen shot of how to use the search engine; it's done me loads of good so far. Now I'm not only certain that my original problem is still jacked up, but I'm also under the impression that I've screwed up a few different things as well. Any help would be highly appreciated at this point.

I don't have that version livecd. Thank you for your efforts.

I was able to boot into my actual system, Just now I have no idea on what to do next, because I thought I was supposed to be on the livecd. Not sure how that works.

(and above)!!!

"Cannot find EFI directory" I tried this exact same thing 20 minutes ago. I remember it saying this after it didn't work.

So, Nvidia and AMD GPU, puh.

You install with free or non-free graphic card drivers?
But for this I'm not really helpful, stay tuned somebody will know to help. :slight_smile:

I use both because I couldn't buy 2 1060's and I have 3 monitors. I guess I installed with free? becasue they seem to be working fine? I'm just trying to fix the booting issue primarily, that's what's got me stuck at the moment.

When I try doing the "Simple First Start" I get all the way to 'sudo grub-install /dev/sda and then I get the response "cannot find EFI director."

Still trying to fix this. Can anyone out there help me? I've been working on this for 2 days. No luck....

Please go through this topic.

Here's a rough test F pertinent for that OP. Of course his partition is (0,gpt2). So change what applies to you. Remember I had totally no experience with encrytption, but i would suggest that to prevent future incidences like this, make a grub rescue cd with the correct gub.cfg in it.

So here's Test F

TEST F (from test D)

grub> insmod cryptodisk
grub> insmod luks
grub> insmod gcry_rijndael
grub> insmod gcry_rijndael
grub> insmod gcry_sha256

grub> cryptomount hd0,gpt2
grub> set root=(crypto0)
grub> probe -u $root --set=pqr
grub> cat /etc/crypttab

<note> copy the uuid for sda2 and set to $abc

grub> set abc=xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
grub> linux   /boot/vmlinuz-4.19-x86_64 root=UUID=$pqr rw cryptdevice=UUID=$abc:luks-$abc root=/dev/mapper/luks-$abc 
grub> initrd  /boot/initramfs-4.19-x86_64.img
grub> boot

Rodger. Will give it a shot. If it's any help, this was a windows 10 pc, that was on the same drive, untill I installed manjaro over the top of it.

In order for me to run this test.... I have to be in grub. Which means I cannot reply, or read any of these messages until I am back running a live CD. This may take a moment.

Good luck, remember up to here from test A to test f, that's the limit of how far I can go. But you can ping the OP of that link there if you need help too.

ps: I'm not too available these few days, as well.
ps: My name's not Rodger. :laughing:

I have no idea what the format is for grub. (hd0,gpt2) I guess I don't put /dev/sda2/ on there.

Do you mean you don't know if your system is uefi or bios-legacy?
If you don't mean that, what 'format' are we talking about?
Other thatn pinging the OP there, you can ping @AgentS.
He can clear up a few things.

I think it's UEFI, but I honestly have no idea how to even check.

If you can access your OS (installed), checking /etc/fstab should tell you.

When I goto install grub I get the error: cannot find Efi directory

When I type /etc/fstab I get bash: /etc/stab: Permission denied.

Of course. So try with both. One at a time.
