cant install windows 7 in the preinstalled windows 8 laptop

You wouldn't install to UEFI with an Active partition, so just proceed with the steps given in post #42 to try another Legacy BIOS install now that you're following the steps closely. Make doubly sure you're not missing a single step or sub-step.

If that fails then try UEFI install, booting into UEFI DVD choice to proceed as shown in UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.
Make sure you delete all partitions to create/format New as shown.

Are you removing the DVD after the first reboot?

The DVD is left inside, not removed.

Doing a UEFI install, see what happens...

Glad to hear it.

As a reminder, if you'll stick with the tools and methods given in Clean Reinstall - Factory OEM Windows 7 then you'll keep a perfect install for as long as you do. These are based on what works best in tens of thousands of installs we've helped with here.

You can mark the thread Solved at top if there's no other issues we can help with now.

thanks for this useful info... :)

I have a Samsung book 8 ultrabook. It started with win 8. I imaged it onto a Samsung 256 ssd. Icant stand win8 so im getting around to converting to win 7 pro.(( the disk is an oem for " use on refurbs.)) first I tried creating new pattition to dual boot then dumped second partion. To install over win 8..im condensing time and actions. Then I repartitioned whole machine to fresh install win 7. I cannot get it installed I have multiple problems. Closest I get..all files copied and it starts to uncompress files and reboots. I even lose bios recognizing anything but a usb in usb ports and when I try to change boot order with dvd plugged in, nothing is listed in bios....grrrrrrrrrr
