The external HD has booted by the qemu BIOS normally, but not by the computer's motherboard. To boot with Legacy BIOS, I backed up the first 1MiB of a flash drive created by Ventoy, backed up the original partition table of the external HD (sudo dd if=/path/to/external/hd of=partitiontable.img skip=466 bs=1 count=64), restored the backup of 1MiB to the external HD (the first partition of the external HD also starts in sector 2048) and then I restored his original partition table (sudo dd if= partitiontable.im g of= /path/to/external/hd seek=466 bs=1 count=64). I was able to install Ventoy and boot with UEFI (creating and restoring the second partition). As in my other post, I'm trying to turn an external HD into a bootable Ventoy disk without losing my current data (I don't have another disk to backup it). In this Video Step by Step Instructions are given on how to Boot HP Laptop from USB Flash Drive.Often USB Drive is not detected by laptop which results in US. Sudo dd if=/path/to/flash/drive of=MBRandGAP.img bs=1MiB count=1Īnd as a question for the developer, maybe I am suffering something similar.
