Original GitHub issue: https://github.com/netbootxyz/netboot.xyz/issues/1726

that issue reopens https://github.com/netbootxyz/netboot.xyz/issues/1070 as that error (still or again) exists for UEFI and legacy boot, despite comment:
https://github.com/netbootxyz/netboot.xyz/issues/1070#issuecomment-1050603259

The commit solved the issue partly. When booting is using UEFI it works perfectly. When used in Bios mode there is still an error which also was discussed here flatcar/Flatcar#586 (comment). [ 0.932433] Initramfs unpacking failed: invalid magic at start of compressed archive

I see the follwing in either boot mode on Lenovo Thinkcentre M600
