PC won't boot from usb?
A few days ago I upgraded an old Win7 to Win10 and had several subsequent problems. I now want to reinstall windows cleanly, but have the problem that my BIOS or whatever does not recognize my USB boot stick. This has already been used on other devices and has been reinstalled several times to avoid errors. The BIOS is an F.6A Bios from HP, just like the old laptop. The stick is not a USB3.0 stick, at least it is not blue. There are still some unfamiliar terms in the BIOS. (i.e. USB floppy, USB CD / DVD ROM drive / USB diskette on key / USB hard disk). But they have nothing to do with my stick, since everything with USB is higher in boot priority than the system. These settings are all available regardless of whether I have the stick plugged in or not. I look in vain for setting options such as legacy boot or secure boot!
If anyone still has an idea, I would be very grateful!

sorry for the picture quality…
It is possible that the bios does not support booting from usb at all.
Even if he can do that, it may be that some USB sticks are only recognized temporarily or not at all.
But somehow you have to be able to boot from the outside, right?
Should I try it with a cd and where can you find which ones are big enough and not only have 700 mb?
With an old laptop from me only went from DVD and floppy via usb. My current laptop just doesn't like some USB sticks to boot, but gets along well with others
Okay so just try it out with a few sticks? And what is floppy? Sry am probably too young… And is there a possibility to format a stick in such a way that the BIOS thinks a floppy is infected?
This is still an old BIOS, the predecessor of UEFI.
The BIOS does not support booting from USB or it has problems with it. But there's the following solution: The Plop Bootmanager Six. This is a boot CD that contains a USB bootloader. This then gives you the option of booting from USB even if it is not supported by the BIOS. Here is the download:
https://download.plop.at/pbm6/pbm6-test-20210119.zip
Then unzip the zip. Then you have 3 folders: 1_native 2_bios and 3_4blind. Go to the 2_bios folder. Then in the cdrom folder. There's a file called pbm6.iso. Then burn this with this tool http://www.freeisoburner.com/ on an empty CD.
Then insert the burned CD, plug in the Windows 10 stick and switch on the laptop. Then press F12 or F8. Then the boot menu appears. Just boot from CD there.
This is how the boot screen of Plop Bootmanager Six looks like:
There you can then select the stick. This is then booted. Then you can reinstall Windows 10 cleanly.
Thank you but I have just tried it for the umpteen thousand times and something like that has just happened but Thank you that is important to know
Because it is a dvd win10 but needs a double-layer DVD. Floppy is is floppy disk drive was in you in the 90s, is no longer relevant today
