https://bbs.archlinux.org – Many thanks for your suggestions. I tried it the way you described it. However i am not able to boot from my sd card. In general my laptop is able to boot sd cards. But in my case there seem to be some problems.i find my sd card under /dev/mmcblkp0 therefore i have to use grub2. which is not a general problem, yet i fail to configure it in a correct waymy current grub.cfp:# # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### insmod part_gpt insmod part_msdos if [ (HowTos)

Code: pcie_aspm=force drm.vblankoffdelay=1 i915.semaphores=1 Then, I ran the following:

Code: grub2-mkconfig -o /boot/grub2/grub.cfg And when I look at /boot/grub2/grub.conf, the new arguments are in there:
