Hello, Paloma.
Thanks for the suggestions dated Sep.25 2021.
My guess:
A. The OS of the dead-locked PC cannot read the installation media USB.
B. Due to this, any or all kinds of media USB is useless.
Reason for suck a guess:
The reactions when the USB is plugged in the dead PC & when the power of the dead PC is on:
- The light of the USB is on but not flashing which means not communicating with the OS,
- There is no any indication showing the OS reads the USB, a sound, blink, flash, message . . . .
About Rufus.
Does Rufus initiatively communicate with the OS of the dead locked PC if an installation media USB is made by Rufus & if the USB is plugged into the PC ?
My guess again:
Need something that can initiatively communicate with the OS of the dead locked PC. & then conduct a re-installation.
What do you think?
"Try unplugging all disks by removing the cables and verifying that startup exits this screen." You said. I do not understand this. "Try unplugging all disks by removing the cables" is understood, but "verifying that startup exits this screen." is not understood. Explain it, please?
Thanks.
