Hai Mr.Ashiqu! Started a very good topic
I want to know about Windows set-up.
Before reinstalling windows, backup your data. So your will not loss any data.
Backup your bookmarks.http://forum.daffodilvarsity.edu.bd/index.php/topic,3006.0.html
Backup important documents, photos, videos etc. from "C:/" drive.
when you will format your C:/ drive at the time of reinstalling... you will lost all data.
Installed programs are not data like.(Ms Office, Yahoo! Messenger or any program like that.)
just copy and paste to other drive (D,E...) documents, photos, videos, songs from your DESKTOP, MY DOCUMENT, and from C:/ drive (if any)
If your 1st boot set as a DVD ROM after inserting Windows DVD you can see "Press any key to continue...." press ENTER
MR.Ashiq already shown it in details.
Now the question is which windows you are going to install! windows 7 or Windows XP.
I recommend Windows 7 if you have minimum 1GB ram.
Insert windows 7 DVD..
Restart your PC
"Press any key to continue...." click ENTER
Select your language (English) click NEXT
Tick I agreed License Agreement ... Next
Click CUSTOM (advanced)
Now be careful... "Where do you want to install?" screen will arrive.
Click on ADVANCE OPTION....(Bottom Right)
Select "Disk 0 Partition 2" (2nd one). Former it.... your C:/ drive is formatted now. And your PC have no active virus now
select "Disk 0 Partition 2" (2nd one) and click NEXT
Your Windows Setup will start and show progress .....
After some time 10~30min(depend on your pc configuration) install will complete
