hy im trying to install arch as the third os on my windows / ubuntu machine and i cant figure it out how to set the grub bootloader i have already read the friendly manual but probably also due to my non native English origins i coudnt find an answer to my question witch is during the arch install should i reinstall grub with grub-install ? i would prefer to keep the old (ubuntu) one also because its already customized but unfortunately i cant...if i dont install it i dont have the directory /boot/grub in witch i should place the grub.conf file so should i just create this directory ? i have tried with os-prober correctly activated to generate a new grub.conf but it doesnt pick up the arch install .., what are the files i must have to make grub recognize those partitions as a new os to witch assign a new boot entry ..
Wow thanks so much such a dedication this time i thought i have tried them all ... yeah i should probably have mentioned that i have only arch on lvm while Ubuntu Is still on a normal partition like Windows but i think your test Is still usefull since somehow while i was trying to make arch appear on the boot screen by mounting all its partition from Ubuntu and generating a new GRUB file and fstab i got the same error you had of loading the kernel First i Will defently give It a shot... since its Easier to recognise what grub I'm using if I don't theme them the same way I will skip that step ... I have a feeling that notthing will change because I have already tried to reinstall grub with gru-install (I believe im not removing it first but I'm installing a new one on top ) but I always get the themed one on boot ...
If you reinstall GRUB from ArchLinux and get the Ubuntu themed one on reboot, might be wort going into your UEFI/BIOS and manually selecting which EFI file to boot from. Probably would be labeled “arch” or something similar.
I will defenetly try this 👍🏻
