Is it possible to change default OS at boot?
Hi All,
I'm not sure if Im in deep trouble or if this is something trivial. Please help me out.
I had once tried to install windows xp SP3 (long back) and it had failed.. The result was that I got 2 options (healthy xp and not working SP3) Everytime during boot. I continued working choosing the healthy one. The default always was the corrupt sp3 and if I was not alert to change it it would try to install Sp3.. Say something got corrupted and restart again during which time I would select the healthy Xp.
Sometime back I got Windows 7 and installed the same. Rather than clean up and format my drive I went for an install that didn't delete my other drives. It took a back up of xp and installed win 7. My C drive had 9Gb of space and I continued working. At boot up I now had 3 options.
annoyed at constantly being asked 3 choices at start up I found my way to uncheck the 'time' box in the advanced setting in windows 7. I thought this meant that win 7 would load automatically without asking for other choices.
Now when I start my system it doesn't ask any choices but goes straight to install from the the corrupt SP3 version, fails and prompts for a restart.. At restart the same thing happens again... I am now stuck and can't seem to either boot up windows 7 or get that list of OS to choose at boot..
Are there any options in bios through which I can increase the time so that it displays that list again or can I change default OS to boot there?
I am not sure of installing win7 again as I believe I don't have enough space on C drive and even if I take the pain of doing all the installation will it still go to the corrupt SP3 because no where during installation do I change the time to list the OS on the machine. Plus I don want to lose my data as there is years of work. I do have a back up on an external drive but it is with a friend who has borrowed it for Atleast a month.
In case you ask me to install win 7 again can I just do it in such a way that only the C drive is formatted? But I need to be sure that corrupt sp3 is not there to cause problem at boot.
Please help me I'm in deep trouble. I don't have any other machine to work on and I type this on phone..
If you need any further info please let me know..
Thanks.
