asf Posted January 13, 2016 Share Posted January 13, 2016 Hi there I would like to know, how i could test my bootable USB to see if it could boot in Bios or UEFI, and how it would boot (seethe menus etc.) without needing to shutdown my computer, or even unplug the USB to plug it into another Computer (that i don't even have) Basically, a bios firmware as a program. I believe there has to be a way Thanks Link to comment Share on other sites More sharing options...

asf Posted January 13, 2016 Author Share Posted January 13, 2016 Just now, aoham said: Try MobaLiveCD http://www.mobatek.net/labs.html Thanks, i know about it, but i can't seem to figure out how to visualize a efi boot mode, even more i don't even know in which mode this tests (as i had a usb that booted in this but didn't boot on a actual computer). Thanks again Link to comment Share on other sites More sharing options...
straycat19 Posted January 13, 2016 Share Posted January 13, 2016 I test my boot drives using VirtualBox. Link to comment Share on other sites More sharing options...

I believe there has to be a way Thanks Mostly I am using RMPrepUSB which has USB emulation in QEMU with write enable. I always make the bootable usb and test using QEMU Emulator (F11). and if you want to emulate USB booting directly in QEMU, than read this. How to emulate USB booting using Qemu Manager and if you want to test UEFI or 64bit, than read this. How to boot directly from a USB drive using an Emulator or VM under Windows Hope it is clear now Link to comment Share on other sites More sharing options...

scandal1981 Posted January 13, 2016 Share Posted January 13, 2016 uefi only works on fat32 and requires the /efi/boot/bootx64.efi to work(needs to be done on windows 7), check the folder structure, linux does it too at least ubuntu and mint Link to comment Share on other sites More sharing options...

Some motherboards have implemented uefi booting from ntfs and rufus also supports it. The latest version of Rufus allows seamless UEFI boot from an NTFS partition. If you select a Windows installation ISO, set the partition scheme to GPT partition scheme for UEFI computers and also set the file system to NTFS, Rufus will add everything required to allow booting NTFS partition from an UEFI system. Outside of using Windows installation media, you can also create a "blank" NTFS bootable UEFI drive when running Rufus in advanced mode (enabled by clicking the while triangle near Format Options) by selecting UEFI:NTFS as the boot option. In this case, you will just have to copy an /efi/boot/bootx64.efi or /efi/boot/bootia32.efi on the NTFS partition for your system to boot from NTFS. The way it works is by adding a small (256KB) FAT partition at the end of the drive that contains am EFI executable that loads a Free Software (GPLv3) NTFS EFI driver and hands over the boot to the regular EFI bootloader on NTFS partition. This allows the installation of Windows media that contain an install.wim larger than 4GB and other stuff... For more on this see the UEFI:NTFS project on github. https://github.com/pbatard/uefi-ntfs Link to comment Share on other sites More sharing options...
