NOTE: Yung images kuha koh lang sa internet pero yung tutorial ako gumawa, baka may magviolent reaction eh.hehe.
Formatting a computer and have a fresh install of Windows 7
1. Open up your pc and press DEL (delete) to enter bios setup (nakalimutan koh ilagay yung step na ito dun sa tutorial ng XP)
note: normally delete is pressed to enter bios setup pero minsan may option din na ESC or F1 or F2 or F10.
2. On your bios setup, change your first boot device to CD/DVD rom then change the second boot device to your HDD.
3. Save the changes you have made (makikita sa baba ng screen kung ano ang pipindutin) and insert you windows 7 CD/DVD in your CD/DVD rom then reboot our computer.
4. Press any key for the computer to boot from the cd. (parang yung sa windows xp)
5. Then again wait until windows setup has finished loading files.
