Issues booting Hiren's Boot CD to Laptop

Spec_tech · Monday at 2:23 PM

Hi everyone. I'm not sure exactly what forum section to put this in, but it basically involves trying to boot some bootable ISO's to a laptop and it not working properly.

So i have a Dell Precision M3800 that i'm trying to get to boot Hiren's Boot CD with a multiboot installer such as YUMI or Ventoy.
I already confirmed the Hiren's ISO is ok by booting it to a Virtualbox VM and it boots fine.
The laptop has an MBR partitioning setup, and i've already turned off secure boot, TPM, and set booting to Legacy instead of UEFI.

Now I know that YUMI basically uses Ventoy now, so it's the same thing. But i've tried using both YUMI and Ventoy to try to boot to Hiren's, but it won't boot past the boot mode selection.
I can boot to the USB's, and i can go through the selection menu to pick the Hiren's ISO, but when it gets to the boot mode selection and pick "Boot to normal mode" it just flashes black real quick and then freezes on the boot selection screen.

I'm trying to figure out if this is because Ventoy/YUMI format the flash drives with exFAT and UEFI and that's conflicting with the laptops MBR partitioning or something.
Can anyone confirm if this is the problem or if it's something else, and how to resolve it?

Well, MBR and UEFI don't work well together. So, switch the USB creation to MBR/legacy and try again.

I just checked the flash drive's partition style and it shows it's MBR. But when YUMI/Ventoy format it, it puts an EFI system partition on there, which i don't know if that messes with how the laptop sees the partitioning.

Ventoy you can actually set what partitioning style you want, whereas YUMI won't let you. But it looks like with whatever tool they're formatted with, they still stay MBR partitioned.

YUMI also defaults to the exFAT filesystem, whereas Ventoy you can actually pick and i've set as NTFS and many others before

If you make the drive on a UEFI system by default it will use uefi unless you go into options and change it to MBR.

The system I use isn't UEFI partitioned, but YUMI uses Ventoy and Ventoy is UEFI-based I think, as it puts an EFI partition on whatever flash drive you use

I found on the laptops' boot selection screen that it gives the option to boot to USB's via Legacy/MBR or UEFI boot.
I've been booting to the legacy option this whole time. Once i booted to the USB in UEFI mode, then all images finally started booting.
