I fix the CDROM so it boots, then I boot the NT 4 CD, run the repair install. Usually NT 4 is booting again so I get to install SP6a (again) and maybe a few drivers.
About 1 to 6 hours work depending on the machine configuration.
At some point a few weeks ago, my cd-rom refused to read CDs. The BIOS would recognize it, WINNT would not. Replacement of the CD-ROM by my favorite hardware guy didn't work either. After several bootings, I took a look at my Event Viewer and notice a conflict of devices, ATAPI and VIADSK. One was assigned to scsiport0 and the other to scsiport2, but to the same address. I opened the Devices in the Control Panel and noticed that both had Start-up as Boot.
Then, I did something STUPID. I changed both to automatic.
Upon rebooting , BSOD.
How do I get my system back gracefully.
I can boot with a DOS 6.22 disk and can access the C:drive. FDISK shows 2 partitions. Partition has Status A and system = FAT16. Partition 2 has no status and System = 7. There are 2 extra lines with ?%? in the Partition Col. The first of these has a status of 3; the type is unreadable; system is 6. The second of these is blank.
After booting with DOS, I have copied atapi.sys, ntldr, Ntdetect.com, boot.ini, and bootsec.dos from an old back up of the root and WINNT directory.
What is the meaning of
Restart and set the recovery options in the system control panel
Or the /CRASHDEBUG system start option.
