Couldn't manipulate them in Windows, and I'm lazy. Never had much luck with flash drives with more than one partition. Can't say how common that is but IIRC I've also had more recent ThinkPads boot in legacy mode without the active flag set. I've had several machines that required the "bootable/active" flag ("a" option in fdisk, "active" command in DISKPART) to be set to boot in legacy mode. And I have been using this stick (and others like it) on several other machines for a very long time without issue (none are UEFI however). I would have expected the legacy boot mode to boot anything that a BIOS system could. Up until today I never had a real UEFI host to try things on. Perhaps that is the problem? I've just looked in gdisk and can see there is a 'legacy BIOS bootable' flag. I have not set any "flags" on any partitions.

Another partition is formatted vfat so it can be used as a plain data stick in windows machines. All hand-configured but that is all irrelevant seeing that I can't even get Grub to load. It has a BIOS Boot partition (gdisk type EF02) and an ext4 partition (gdisk type 8300) which contains the Grub files in /grub and a load of isos which the grub config is configured to boot from a menu. It uses both GPT and a protective MBR configured in such a way that windows machines that use the MBR only see its data partition (see below). It uses an up to date Grub 2.02 configured for BIOS booting. Hi the stick is, like yours I expect, a homebrew "swiss army knife". I tend to use a live Ubuntu's grub2, or stand-alone grub2, on my "Swiss Army" flash drives to boot a bunch of stuff: assorted distros via ISO, forensics tools, Acronis, etc. Fancy-schmancy flash drive builders like Rufus and others aren't necessary.įedora (IIRC) and Ubuntu (for sure) are bootable in Secure Boot/EFI mode. If that isn't available use something like the (free, and very useful0 7zip.
HIREN BOOT USB ADD BOOT TO PARTION ISO
To extract the contents of an ISO to a flash drive: with Win 10 just use Windows explorer to open the ISO and copy the files. In that case one has to be careful to select the boot mode in BIOS or one could boot (and install) in the wrong/undesired mode. It's entirely possible to build a drive that can boot in both Legacy and UEFI mode by copying ISO contents to the drive and also running grub-install. An active partition can fool some BIOSen into trying to boot an EFI-bootable drive in legacy mode. The way I make bootable flash drives from modern distros that are EFI-bootable: copy the _contents_ of the ISO to a MBR/FAT32-formatted flash drive that DOES NOT have an active partition. What version of grub? What distro - if any - is the base install? Is it legacy or EFI, or both? Live or ? How is the flash drive formatted? MBR + FAT32? Is it intended to be UEFI-bootable? If it's a legacy-boot-only thing, does it have an active partition? etc, etc. If I can't get this to work then it's going back.Īt the risk of going off-topic, if anyone has any useful thoughts about why my USB stick doesn't work, it'd be much appreciated. I tried two separate USB sticks and I tried both USB ports on the right-hand side of the computer. It works in about a dozen other machines that I use it on regularly.
The USB stick has Grub on it and boots Linux distributions. Same result.įifth attempt: as before except that I set Startup > UEFI/Legacy Boot to Legacy Only. Same result.įourth attmpt: as before except that I changed the boot priority to put legacy first. Third attempt: as before except that I additionally set Startup > UEFI/Legacy Boot to Both and tried again. Disable secure boot ( Security > Secure Boot). Second attempt: Power On Hit Enter at Lenovo splash screen Hit F1 at Startup Interupt Menu to eter the BIOS Setup. Force power off by pressing and holding the power button. Here is what I have tried.įirst attempt: Power On Hit Enter at Lenovo splash screen Hit F12 at Startup Interupt Menu Select my USB drive from list Hit Enter screen goes back for about one second and then the F12 menu reappears like nothing happened. In case it makes any difference I am trying to do this before ever booting into Windows. I am trying unsuccessfully to boot it from a USB stick.
