Can't Boot or repair - NETIO.SYS missing/corrupt
I returned home today to find my computer off and not able to boot. My wife said all she had done was web browsing and then sleeping the computer. At this time the computer tried to Auto-repair the startup but would cyclically fail (indicating an issue with NETIO.SYS). I performed the following steps:
1. Did a scandisk with repair options that recovered some files on the boot SSD (all future scans have been clean)
2. ran bootsect /nt60 SYS /mbr bootsect with a few more options including ALL
3. Tried to use windows Automatic Startup Repair and still had cyclic failures and got worried that perhaps there was a virus.
4. Re-flashed the BIOS with an updated BIOS
5. Ran Avira from a boot CD, scanned for viruses, and only things that turned up were a java virus in a random file or patch. Seemed unrelated to any of the problems.
6. Ran bootrec to restore the MBR
7. All throughout this process tried the windows Startup Repair with no luck
Now instead of automatically going the Startup Repair it tries immediately displays a Windows failed to start problem. With NETIO.SYS and a status of 0xc000098 (Windows failed to load because a required file is missing, or corrupt). I don't have a recent enough system restore point to recover from. I am desperately trying not to do a full re-install to preserve installed program data. Startup Repair from DVD of course still fails with a detailed signature of: StartupRepairOffline - AutoFailover (sig5) - CorruptFile (sig7).
System info:
MB: Asus P6T SE
OS: Windows 7 Home Premium - 64bit
HD: Intel 80GB SSD for boot, secondary 1.5TB data drive
Any thoughts?
Thanks,
Robert
