Dual booting windows 8 and 7, stuck on starting up screen.

So what I want is to dual boot windows 8 and 7, but I have a little problem. First some info about my laptop: It came with windows 8 pre installed.

I also have a window 8 recovery stick just in case

I made a second partition for windows 7 and gave it 150GB. When I made a windows 7 usb stick it was for some reason not bootable so I decided to install it into the partition from within windows 8. After it was done copying files the second option (I don't remember what it was) got to around 20-30% and it restarted my laptop, and it took a while at the starting windows screen, after that it got to updating registry files and back to starting windows. I waited a hour for it load but it just didn't want to load. It was stuck at Starting Windows. I shutdown my laptop and tried to go into windows 7 with safe mode but it got stuck on safe mode loading screen too. What am I doing wrong?

So what I want is to dual boot windows 8 and 7, but I have a little problem.

YES & NO, down to your UEFI/BIOS firmware setting.

As this a OEM manufacturer's PC with Pre-installed Windows 8.

1) Downgrade to Windows 7.
Downgrade Windows 8 to Windows 7
Warning you must have the UEFI/BIOS firmware setting in Step Three set.

Make sure you read the NOTE at Step three.

2) If Using a USB Pen drive on a PC with a UEFI BIOS.
USB Pen drive need to be formatted to FAT32 as in
UEFI Bootable USB Flash Drive - Create in Windows
Take note of Step 11 for Windows 7.
Also you will need to use a USB 2.0 port, as there are no USB 3.0 drivers in Windows 7.


You will need to buy Windows 7.

Hi,

The proper way to install is using a bootable media either dvd/usb. Make your USB stick bootable first and try doing a fresh install. it should work.

But from your comments i see the second step is "Expanding your files " which ran for 20-30%. may be the OS is corrupt

Format the stick with Option One from UEFI Bootable USB Flash Drive - Create in Windows.

In BIOS setup disable Secure Boot, be sure to boot the stick as a UEFI device. With some models it requires enabling CSM with UEFI Boot First. Let us know what your settings choices are if you get stuck.

So I followed the tips you guys gave me and I managed to make the usb bootable, but when I booted from the usb it showed me loading windows files and then Starting Windows. It got stuck on that screen again, yet when I do the same in virtualbox after starting windows screen it immediately goes to the installation page. So the problem is not the windows 7 iso I got from my dvd a long time ago. I would like to try it with the dvd but I can't find and also I really don't want to buy it again.

My BIOS settings:

Are you booting in UEFI mode?

You never have to buy the DVD again if you have the license. YOu can use the latest official ISO in Step 1 of Clean Reinstall - Factory OEM Windows 7 burned to DVD or written to flash stick with the tool in Step 2. The other steps also apply to retail and will assure you get and keep a perfect install, based on what's worked best in tens of thousands we've helped with here.

Try disabling Turbo Boost until after install, and enabling USB 3.0. Then be sure to use the correct port for whichever flash stick you have 2.0 or 3.0.

As Ray points out above you must boot the installer as a UEFI device to install in UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.

If this fails what always works is to Bypass UEFI to Install WIn7

This is the boot menu I get:



And this is what my hdd looks like with all the partitions and stuff:


I don't want to get rid of windows 8 because I don't have a dvd or serial key or whatever for that. On my dads windows 7 laptop there is a little label with the serial key for his windows 7 but on my laptop there is only a label with the windows 8 logo on it. I would like to keep my windows 8 installation because ill probably need it somewhere in the future and this way I wont have to buy it.

   Warning

THE BELOW WILL NOT WORK, IF YOU HAVE NOT SET THE UEFI/BIOS firmware CORRECTLY.

If you have not done the above, Windows 7 x64 will not boot to finish the install.

Use the Windows 7 x64 SETUP.EXE from the DVD, from the Windows 8 desktop.

Instead of spinning mythology about Windows 8 why not ask us so we can explain it to you?

Win8 is coded to your BIOS so that it will reactivate on that machine whether it's reinstalled from an installer which can be provided for Clean Install - Windows 8. You can also always run Factory Recovery from its hotkey at boot, or use Recovery media you make now for such a reinstall - although it's not as good as the Clean REinstall it saves a lot of time if you're not picky.

So if you cannot get it to install in UEFI then once you make the bootable Recovery media as a backup you can also choose to Bypass UEFI to Install WIn7 which always works.

I have installed Win7 in a Dual Boot on many Win8 machines in order to keep 8 on the HD until I decide if I want to keep the PC. In every case I had to Disable Secure boot, then boot the installer as a UEFI device. You have no UEFI devices showing in the boot menu, which makes it appear you have disabled it in the BIOS, most often done by enabling Legacy Mode or changing the setting for Compatibility Support Module (CSM). So check those settings now, expand them to take a camera snap if possible and post it back so we can help you choose.

In addition if you're using a flash stick use Option One in to make it a UEFI Bootable USB Flash Drive - Create in Windows . It will not boot otherwise.

So let us see the choices in BIOS setup for UEFI, Legacy BIOS, or CSM. You may have to dig through each tab to find them.
