Imagine you have Hiren's Boot Rescue CD on a flashdrive on a flashdrive, and your intention is to restore windows password, but you cannot access the bios, because it is locked with a password. I searched on the internet and did not find anything, just tutorials on how to boot from usb with modifying bios, but they were useless in my case. Is there any way to boot from usb WITHOUT:
- Modifying bios manually
- Accessing any OS installed on the system
Note: I will NOT use this for destructive purposes, I'm just interested in what to do in this case.
Regards

This really depends on the BIOS settings - in some cases you can't do it without modifying the BIOS.
I would not recommend it, but it should be possible to open the system and remove all bootable disks, then see if the BIOS will boot from USB. If the BIOS is set to read hard drives first, then anything else - not an uncommon setting - it will work. The difficulty you may have is plugging the hard drives in afterwards. Theoretically this can work as SATA supports hotplugging of disks (and yes, I do it routinely - on known hardware). It is, of-course, possible you will land up frying your MOBO or hard drive.
If I were trying to reset a computer password without BIOS access, I'd be inclined to remove the hard drive and put it in another PC, then perform the appropriate reset operations.
