I am trying to fix a computer that cannot boot. Sometimes the errors are shown too quickly for me to read. When I try to boot Windows normally the following happens shows Windows starting screen restarts I believe it tries to pixy boot Shows "PXE-MOF: Exiting Intel boot agent" and "1962: No operating system found" keeps going through a cycle where it says DHCP.../ (where the slash rotates) and says the client mac addr and GUID and says "PXX-E53: No boot file name received" When I try to boot windows into start up repair the following happens start up repair scans for problems and takes a long time and sometimes hangs finds that it could not repiar the computer automatically and gives a bunch of information, one of which is "Problem signature 07: CorruptRegistry" I've opened the box and checked the cables and blew compressed air to get rid of dust. I went into the bios settings and the setup utility says "IDE Drive 0 500GB SATA1" There are documents on the computer that should be saved. I suspect that there are two partitions. What is the next step?
