A few days ago I received a message about restarting my computer to fix system errors. I restarted the computer something started to do and after a while it showed that repair at startup failed. I could only enter the advanced options, but nothing can be done there. I tried to install the system with a pendrive but when it comes to the end and the computer restarts it is still the same, i.e. only the motherboard logo is displayed and later as if it restarts again all the time. Please help.
