How to boot the system if there is no bootloader, and if the PC does not see the USB flash drive?

Question

Windows

On an old computer - G31MXP with Pentium (BIOS-P07), the Windows-10 bootloader crashed. The PC does not run the installation media and I installed the OS via easy bsd. Can you tell me how to return the OS?

Answer 1

Old mothers at the boot stage do not see flash drives larger than 4GB, and now it is not so easy to find less, you have to look specifically. They don’t know how to GPT and can’t boot from a disk larger than (or equal to) 1TB.
Also, very old mothers may not be able to use usb-hdd at all, but these are really quite ancient. in this case, either LiveCD will help, namely the CD, well, or the hard drive has grown with the appropriate software.
