hi, after a week trouble i was able to fix it partailly. now i was able to access windows 7 ( now i am posting this from windows OS only)
Things i have done.
1.Booted to safe mode
2.Disabled services that are not critical (as i searched through google for ptimizing win7)
3.Made it clean boot by removing all the startup and services.
4.Find out the culprit as said in microsoft website about clean booting.
5.Find more than 5 services non microsoft services: Adobe switch board, Autodesk licensing service, AVG watchdog, AVG IDS agent and google update service (gupdate and gupdatem) and microsoft services more than 1 alphabatically (A, B, D, H, K, N, W). Unable to find more individual services as it is taking a lot and lot of time restarting system. thats almost more than 20 times of restart. fed up.
6.I scanned sfc and it fixed some more errors.
7.from windows XP (parallel os) i donwloaded tha above said windows 7 sp1 DVD.
8.Got to remember that my DVD drive is not working and 2 days of trying to update drivers and found nothing. finally from event viewer i found its because of faulty cable and replaced it.
9.no read or writing from windows (neither from 7 nor from XP) but able to boot with the DVD in dvd drive.
10.Now how to write the downloaded DVD (win7 with sp1 integrated) to write and repair my windows 7? (drive is not working only in windows
11.Installed MagicISO and mounted the cd in windows 7 and tried to upgrade install of win 7 with win7 sp1
12.it says it can upgrade only win7 with sp1 already installed.
13.i tried to find by my windows update but it is not listing in updates. i installed remaing 1 update about win defender
14.what to do next? how to repair my win7 without DVD drive working?
15.Can i download sp1 offline version seperately and install it and then repair with the DVD?
16.or if i select to install win7 as new install (not upgrade) and after restart will i get repair option? (note: this is from virtual cdrom)
17.if i start it above way and after restart by the installation is it able to access the DVD from virtual drive for remaining part of installation?
