Got Toshiba Satellite U940-B484 (PSU6VV). Has windows 8 on, but I'm trying to install Windows 7 instead.

When I cam across the part where I choose the partition where Windows 7 will be installed on, there were no partitions listed at all!

That's what been showing!



I tried to pull the partition through "Load Driver" but it didn't work out.

The laptop might have 2 SSD hard drive merged into one partition, but I'm not quite sure.

Thanks in advance,

Did you change the setting for UEFI to Legacy/CSM? That's required to install 7. You may also need to convert your drive from GPT to MBR.

If you have 2 SSDs in RAID you will need to provide the RAID controller drivers to the Windows 7 setup. It will say "if you have any drivers, put in disk with them now". Find out the exact drive configuration for your laptop.

This may be it also unless your RAID setup (if you're installing under RAID that is) is software controlled. Software RAID uses the IRST software instead of dedicated hardware.

I wish if I know more about RAID, but I haven't gone into that before.

I'm wondering how can I provide the RAID driver to the Windows 7 instillation, and how can I find out the exact drive configuration for my laptop!

Thanks fellas

Look in the specs for your laptop, will be in the manual or in the purchase order for what configuration it has.

Get the motherboard drivers and put them on a disk, then point the Windows setup to that when it asks. If that's the issue with installing things. If they download as a single file (like an EXE) you'll need to extract them into the actual driver files.

You will need to know this first. If you have two SSDs in RAID, then follow hang-the-9's advice on set up. If no RAID, then your drive mode needs to be set for AHCI or SATA in BIOS.

It may be better to make a new topic instead of hijacking this one since your model is slightly different from the OP's.

If this was a Windows 8 system, make sure that, if you're running a UEFI system, Secure Boot and UEFI are both disabled (look for "UEFI" disable or CSM/Legacy BIOS - enable).

You may also need to use the diskpart command line to delete the current volume and/or set up the appropriate disk type (most likely MBR).
