The computer can't boot into the system, only two lines 1. Priority of boot options in biss mode (PO: ST 100LM24h).

1) Software first, then hard. Reinstall the operating system, do not install software, patches, drivers, etc. See if there is anything wrong with the boot. Don't install drivers, patches and software step by step, and don't install them if you find them inappropriate.

Please note: if you restore or reinstall the system, when installing drivers, patches, software and other things, you must not install things that affect your accident this time, otherwise it will be futile to restore or reinstall.

2) If it is caused by hardware problems, repair is recommended.

3) What's more, it has something to do with improper operation before you turn it off? For example: playing games, watching videos, operating big things, and using computers for a long time? Or downloaded something inappropriate, the fault won't happen for no reason, right?

If this problem is caused, please repeatedly try to turn the machine on and off for a period of time. You really can't reinstall the system. If you can't install it yourself, take 30 yuan to the maintenance office and ask the maintenance staff to help you.

As long as you pay attention to your computer, it won't be like this when you turn it on.

Ask me any questions.
