[SOLVED]Grub fails to open dm-crypt+LUKS volume on boot(Waiting 10s..)

I know there are quite a few solved posts like these but it's usually because of "mkinitcpio -p linux" not being regenerated.
My problem is after boot Grub says:

running hook [udev]
running hook [encrypt]
Waiting 10 seconds for device /dev/disk/by-uuid/d1d0825c-25d1-4cbe-811f-725d9ef8d034>...
ERROR: device 'UUID=d1d0825c-25d1-4cbe-811f-725d9ef8d034' not found. Skipping fsck.
ERROR: Unable to find root device 'UUID=d1d0825c-25d1-4cbe-811f-725d9ef8d034'.

Here are all the files that I think would be needed for this:

/etc/fstab

# 
# /etc/fstab: static file system information
#
# <file system>	<dir>	<type>	<options>	<dump>	<pass>

#/dev/sda5                               	/boot     	ext4      	rw,relatime,data=ordered	0 2

Things I tried:
Replace this line in grub.cfg with

 linux	/boot/vmlinuz-linux root=UUID=d1d0825c-25d1-4cbe-811f-725d9ef8d034 rw cryptdevice=UUID=d1d0825c-25d1-4cbe-811f-725d9ef8d034:cryptroot quiet 

Do mkinitcpio -p linux but the hook ecrypt is there, so I assume it's a grub issue.
In

 /etc/default/grub 

replace GRUB_CMDLINE_LINUX="cryptdevice=/dev/sda6:cryptroot" with actual UUID, etc.

Grub config was made with

grub-mkconfig -o /boot/grub/grub.cfg

Grub was installed with

grub-install --target=i386-pc --recheck /dev/sda

Re: [SOLVED]Grub fails to open dm-crypt+LUKS volume on boot(Waiting 10s..)

Ok, I got it to work. After 5h of messing with this thing I gave up and installed everything from scratch.
And it worked.
I did nothing different, the files look the same (except different UUID)

Welcome to the forum :-)

Please remember to mark the thread as solved https://bbs.archlinux.org/viewtopic.php?id=130309


When posting configs, code or command output, please use [ code ] tags, not [ quote ] tags https://bbs.archlinux.org/help.php#bbcode

like this

It makes the code more readable and - in case of longer listings - more convenient to scroll through.
