I´m getting various BSOD when installing FS. After the Bluescreen it hangs up on Searching for updates

This is either a disk drive failure or a Windows failure. Windows is either writing or reading a memory page from a part of a disk allocated for paging. But there is something wrong with the memory adresss on the disk. Either Windows has a broken memory allocation table, there is a hardware problem with the disk or disk controller, or there is a problem with either the disk partioning or formatting. The numbers on the BSOD screen can help you troubleshoot this problem with Microsoft. It is not a MSFS problem.
