Well indirectly anyways !
Sequence of events (or screwups on my part)
1 - Vista SP1 started with networking problems "NVIDIA nforce controller dirver not working properly or installed" - Tried to uninstall driver - get new drivers, unistall let microsoft provide driver with SP1 - uninstalled driver and went back to old version of driver before Vista SP1 - end result same - NO Internet.
2 - So this smarty pants went and got old NIC card and installed in PC - disabled onboard lan card in bios and booted up. Windows started but no change in network connectivity. The lan card also had a scsi controller by Symbios. Rebooted and went to Symbios settings(F6 at bootup) and made all setting auto (Did not know what I was doing but did it anyways). Reboot and hosed the boot up. From this point onwards - does not go to windows and stops with Cannot find driver error - and stops there - only thing can do at this point is reboot and reach same place again. I believe the drive error was a result of going to default setting in bios after a few reboots.
3 - Got a another new Lan card (NIC card is official name) and no difference - so uninstalled all cards and went back to on board lan - but same cannot find disk error. Then monkeyed around in the bios and found that there were no setting for hdd in bios and then went and looked for them in "auto" from the bios utility and FOUND THEM.
4 - But still cannot find boot information on either of the two drives. maybe i deleted or overwritten on the autoexec.bat (Do we still have those in vista pcs???)
Final Status - The end result is that all i can do is access BIOS and make any changes to BIOS settings - but wont go any further than that.
I tried to get Vista boot disk - well i found that now I have Vista SP1 maybe the Vista boot disk may not work.
Fear - I do not want to reinstall Vista (Have disk) but would have to reinstall all the software on it (A pain) and definitely do not want to reformat the hard drive as I have some family pics not backed up. (Have two dvds worth of data backed up in December 2007 - so am not that bad with data backup but will lose all photos since then)
Help: The rambling was to give a background of the problem instead of "My PC wont boot" story. Any of you with more experience with similar issues - I will be happy to hear.
I do not have a problem to work hard to resolve the issue compared to reloading OS and other applications. Also may learn a lot in the process to "How Not to screw up in the future"
Thanks for your patience in reading my SNAFU..... :$
