New Motherboard Fail Windows Upgrade Please help

Okay so here is the whole situation, 1st i was using windows vista x64 bit until recently i replaced my motherboard seeing as the previous crashed, i bought a gigabyte x58 UD3R and x3 2GB DDR3 memory sticks, with replacing the motherboard i was told i would need to reinstall windows, seeing as that the mother board, hard drive, etc all came together because i bought the computer straight off the factory so with replacing my motherboard and memory i don't have a windows vista x64 bit disk to "reinstall windows" so i just bought windows 7 upgrade disk hoping that i could just instal windows 7 with the upgrade disk. But when i load the disk i click on custom(advanced) installation and the installation begins it completes "expanding files" then installing updates etc then restarts. After my computer restarts it comes right back to the windows 7 installation screen again and ask me to reinstall windows 7 AGAIN.. and this is on going repeating itself over and over and over until my hard drive is full. I just formatted my hard drives to get all my space back but, i want to know why my computer isn't booting windows 7 when it says it's been installed? It seems as if it is only booting off of my CD/DVD drive and i don't know what to do please help!

If you manually changed your boot order to boot from the CD/DVD first, you have to switch it back to the hard drive on the first reboot. You only want to boot from the CD/DVD once to start the install.

There should be a message during POST to the effect 'press any key to boot from CD\DVD' If you dont press anything it will go to the next device in the boot order, providing that is the HDD\SSD then there would be no problem.

Clean Install with a Upgrade Windows 7 Version

When i try to boot up my computer without a cd/dvd in the drive it goes to a screen saying Verfying DMI pool data..... and under it after like 5 minutes it will say CD/DVD Boot: Enter a systems disk and press enter, what kind of disk is a systems disk? because it says i completed the windows 7 install soooo?

Also it seems as it is not regonizing my HDD because when i tell it to boot from HDD it skips it and jumps straight to boot CD/DVD

Does the HD show up in BIOS setup? What is it's SATA controller setting there?

Try setting HD first to boot, then boot the 7 DVD from the one-time BIOS Boot Menu key given on first boot screen.

During installation, use Custom>Drive Options to delete everything on HD, repartition and format for install. Accept the 100mb SysReserved partition which places Repair console on F8 Advanced Boot Tools menu.

How do i repartition my HDD after i click delete in driver options?

Click Delete on each partition, then Click New, create as many partitions as you want, format each, install to first partition after the 100mb Sys Reserved which should be issued:

Do i have to instal my C: and D: drivers before i can instal windows 7? because if so i do not have a disk for those two drivers, they came with the factory computer when i bought it without the disks.
