With your help and further internet research, I now understand how to and have successfully created:
Bootable HBCD 15.2 (Legacy BIOS-MBR) USB
Bootable HBCD PE x64 (UEFI-GPT) USB
Bootable SourceForge repair disk (UEFI-GPT) USB
Bootable W10 Install USB-DOS (Legacy BIOS-MBR) & (UEFI-GPT)
Bootable W10 Install USB-ISO (UEFI-GPT)
Bootable W10 System Repair USB (Legacy BIOS-MBR) & (UEFI-GPT)
But I am still a little confused and have not been completely successful in creating a bootable UEFI-GPT or Legacy BIOS-MBR USB with a menu and loaded multiple apps like MiniTool Partition Wizard, Hard Disk Sentinel, CrystalDiskInfo and HWiNFO64 on it.
I have done some research on the various Multi-Bootable USB programs including YUMI, Universal-USB-Installer and Ventoy but still have not been successful in making them work….
How To Make a Multi-Bootable USB? https://recoverit.wondershare.com/computer-problems/multiple-iso-bootable-usb.html Followed their instructions
Ventoy – I have successfully created a bootable UEFI USB with multiple app ISO’s copied from my local drives and the Apps appearing in the menu but when I try to execute any of the Apps, they play dead and I get a message stating “No bootfile found for UEFI. Maybe the image does not support x64 UEFI.”
Step 4: Ventoy is installed on your USB flash drive. Now, you can simply drag and drop ISO files onto the USB drive. Ventoy will automatically detect the ISO files and make them bootable. It's a straightforward process that doesn't require any additional configuration.
My Flash Drive is 64GB with 2 partitions (created by Ventoy).
1St partition named Ventoy, formatted ExFAT, set to Primary Active and 140.88MB usage
2nd partition named VTOYEFI, formatted FAT16, set to Primary Not Active and 27.39MB usage
My ASUS FA507RE laptop bios is UEFI and my SSD’s are GPT………..
Please also note that all the Apps copied to the USB as ISO’s function correctly when run on my laptop…
But All Ventoy Function Keys at the bottom of the Ventoy screen DO function correctly so I suppose I got something right haha……..
I have tried the other available boot option in the Ventoy menu but still same result.
I have tried other USB’s but get the same result
I have even tried it on SD Card (Secure Digital Card) but get the same result
I will continue trying with some of the other Multi-Bootable USB programs to see If I can have some sort of success with them.
Looking forward to your replies….
