Solved Can't dual boot windows 7 with windows 8 ?

[Esmeal]

I just bought a new laptop with pre-installed Windows 8 . I tried to install windows 7 in the second partition so i can use both 7 & 8 . Used windows 7 64x DVD , i started the installation from windows 8 . It went well until restarting where i got two options "windows 8" or "windows setup rollback" which it stops at "starting windows" logo from windows 7 !! ... i tried to boot from the beginning from the dvd(second time with usb)..it didn't boot..instead i stuck again at "starting windows" logo. so i can't even boot from the dvd .

I disabled the Secure boot from the beginning ... i have been searching for a solution but nothing worked .

Do I have to delete all the partitions on the disk then install windows 7 ??..if i do...how to keep windows 8 (i don't have windows 8 DVD) ?? .... please notice i am not an expert in these things so please make it detailed.

if i can't even boot

i have Toshiba Satellite C855D

I have GPT drive and UEFI bios mode (don't know what either of that means but read it might be a problem).

What happens if you (try to) boot win8, so select windows 8 in bootmenu?

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.

As Toshiba has no support for Windows 7 x64 install in UEFI mode, you need to install Windows 8 x64 & Windows 7 x64 in Legacy mode.

From Toshiba Support site.

How to enable CSM for a Toshiba.(Satellite Pro C870, Satellite Pro L830, Satellite Pro C850, Satellite Pro R950, Portege R930, Portege Z930)

To downgrade from a installed Windows 8 OS to a Windows 7 OS, using a Windows 7 recovery media, follow these steps:

1) Boot unit and press F2 to get into BIOS

2) Go to "Security" tab and disable "Safe Boot"

You can make a Microsoft Recovery USB Drive

   Warning

Deleting the Recovery Partition is NOT RECOMMENDED​

   Warning

I personally DO NOT RECOMMEND using this METHOD above, as of the ERRORS you may receive below with the Microsoft Recovery USB Drive.You would be best off using the OEM manufacturer's Recovery DVD's or Recovery USB drive.

I would recommend you making the OEM manufacturer's Recovery DVD's or USB drive.

You can order the Microsoft official OEM Recovery disks from the OEM manufacturer's website.
Toshiba Service Portal - Laptop Recovery Media Services - Toshiba



The Windows Recovery USB drive & Recovery Partition can be very problematic, I recommend you also make a Windows System Image.

System Image - Create in Windows 8

Recovery Drive - Create with USB Flash Drive in Windows 8

System Repair Disc - Create in Windows 8

System Image Recovery - Restore Image on Computer in Windows 8

or
look for a 3rd party ,Backup software, which fully supports Windows 8, uEFI, GPT & Secure Boot.
Which is signed by Microsoft.

You will loose all data on all partitions.
BIOS set up:
1) DISABLE Secure Boot.
2) Set OS boot to CSM.

Windows install:
To clean install:
1) Clean the HD Drive, using Step one in this tutorial:
http://www.sevenforums.com/tutorials/91339-ssd-hdd-optimize-windows-reinstallation.html
than first install Windows 7.
2) http://www.sevenforums.com/tutorials/1649-clean-install-windows-7-a.html?ltr=C
than install Windows 8.
3)Dual Boot Installation - Windows 8 and Windows 7 or Vista

You will need to buy Windows 7 & Product key, also a Windows 8 DVD.

You should be able to disable Secure Boot to install WIn7 in UEFI mode to the partition you made there. I have done this several times on Win8 PC's to see how Win7 runs on them. You won't have access to Win8 unless you turn on Secure Boot. But at least you'll still have it hidden on the HDD in case you need to go back.

Of course as with any install you need to boot the installer to do this. I don't know why you would try to run it from another OS as installs are not done that way ever.
