[solved] Can not boot the kernel on archiso

Hello,

i ask for help with booting the archiso installation medium on my Asus e45m1-I motherboard. I created a bootable usb from the iso as explained on the wiki using gtp formatting and on a second try mbr. Both fail to boot and show only a black screen, because of a known bug in gummiboot.[1] I have read and understood the comments posted there.

A solution was suggested that says you have to use reFFInd instead of gummiboot. I reformatted the usb stick,extracted the image again and did the following steps:
* install refind and replace existing (USB)/EFI/boot/bootx64.efi with /usr/lib/refind/refindx64.efi
* Created (USB)/EFI/boot/refind.conf as described in the bug report [1] .

This time i am able to start refind and get a working menu.
After selecting the first entry rEFInd hangs forever ( waited ~15 minutes ) showing this message:


Afterwards i  tried adding "nomodeset" and removing "pci=nocrs", but it still hangs forever.

It is disappointing that i can not boot arch on this mainboard, while all of the usb keys i created boot perfectly on my lenovo computer in UEFI mode.

The specific kernel on archiso had a problem with the amount of memory installed, and i had to add mem=2048M on the commandline for successful booting.

Re: [solved] Can not boot the kernel on archiso

Seems like kernel mode setting issue, can you try "nomodeset" kernel option, or try removing the "pci=nocrs" option. In my Thinkpad both gummiboot and rEFInd work properly.

Thank you for responding, i added "nomodeset" and rEFInd still hangs at "rEFInd - Booting OS" , the same happens when i remove "pci=nocrs". Still no luck.

Try launching the kernel from UEFI Shell, if the same problem exists then the issue is not with rEFInd but with kernel itself.

Re: [solved] Can not boot the kernel on archiso

Update: It is indeed a kernel problem. After booting the iso in MBR mode, without EFI mode, the boot is stuck at "booting the kernel". Again "acpi=off" and "nomodeset" did not change anything.

Re: [solved] Can not boot the kernel on archiso

Update: Solved now. The 32-Bit Kernel booted correctly, and a quick search revealed i had to add mem=2048M to the kernel commandline in 64-Bit mode.
Now i succesfully booted the archiso with MBR mode, and installed Grub2 bios.
