What method should I use to ensure my laptop powers down using the USB port?
I have a Lenovo ThinkPad but it won't boot from USB. I've checked various settings I could think of.
What error messages appear? The reason for starting from the USB drive remains unclear.
Much more information needed.
I aim to build a bootable ultimate boot disk to diagnose issues on this PC and similar systems. I believe it relates to the euid setting.
It's worthwhile to review the official guidelines, though I note that USB sticks are handled differently for Legacy BIOS versus UEFI even without Safeboot. For instance, using Microsoft's Media Creation Tool on a UEFI machine will format the USB stick as GPT, making it incompatible with Legacy BIOS systems. With WinPE, a bootable USB must contain both a legacy boot folder and an EFI folder for UEFI. Many older devices also impose a maximum capacity limit for bootable USB drives, so 32GB or less is more widely compatible. These compatibility challenges could be resolved by opting for a USB optical drive, which supports booting on any system allowing USB selection. However, this would restrict the number of included tools to around 8.5GB per disc for DVDs. It seems feasible to create bootable Bluray discs as well, but I’m unsure if all computers can handle them, particularly larger BDXL drives.
