Windows 7 installation says I cannot install on GPT drive on my laptop

Hi,
I'm trying to replace w8 on a brand new Samsung laptop.

Titles didn't work and it was a rather inconvenient o.s. for me altogether (you can check here for more).

I’ m running the Windows7 installation, right now, only to find out that W7 won’t install on a GPT drive.

What am I to do? I’d appreciate any help.

Is 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.

First watch this video to understand the new UEFI BIOS vs. Legacy BIOS - YouTube.

If you want to install using UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums. The disk you're trying to install upon now is GPT ready for a UEFI install so you'd need those extra steps to boot UEFI installer and proceed.

If you don't want UEFI but want to install normally then Bypass UEFI to Install WIn7.

And as Theog reminds and you must already know if you've gotten as far as you have, you must disable Secure Boot in BIOS on a Windows Ate computer.

@ICit2lol, theog
I had a look at the supplied links but right now i have no bootable windows on my laptop as the W7 installation was cut off halfway. And yes, it's a samsung laptop with W8 preinstalled...

( @gregrocker i'll check ur links later.. )

i called the samsung support yesterday, they were very friendly but the instructed steps weren't any good.. So they suggested that I should download some software like "pc check" and "destruct" the hard disk so that i can proceed with a W7 installation...

( Why is it that such vivid procedures, like the installation of a o.s., instead of getting simplier it gets harder and close to impossible? )

thanks for trying to help ppl
:)

Yes I agree that UEFI is a can of worms. I prefer normal MBR installs, so consider your two options carefully based on what you learn.

Whichever you decide adapt the steps in Clean Reinstall - Factory OEM Windows 7 which compiles everything needed to get and keep a perfect install.

Samsung said:

1) Enter the BIOS by pressing the F2 key while your system is booting up.

2) Move to the boot menu using the right arrow key.

3) Select 'Secure Boot' and then select 'DISABLED'

4) Select 'OS Mode Selection' and change it to 'UEFI OS'

UEFI & CSM OS

5) Save the changed settings by pressing the F10 key and then restart the system.

Very easy on a Samsung.

1) DISABLE Secure Boot.

2) Set CSM to UEFI & CSM OS.



3) Install Windows 7.

the working solution was this:
during the W7 installation, at the moment when i needed to format the hard disk, i pressed Shft-F10 and got a command prompt where i could give the following commands:

Code:

DISKPART
  SELECT DISK 0
  CLEAN ALL
  CREAT PARTITION PRIMARY SIZE=150000
  FORMAT FS=NTFS
  ACTIVE
  EXIT

where DISK 0 is the destined hard disk (LIST DISK shows a list of the disks) and SIZE is the prefered partition size in MB.


Anyway, i got through with the installation only to find out that there are no W7 drivers for my samsung laptop (np275e5e-k01gr) and it cannot connect to the internet because W7 cannot recognize the ethernet card.

I inspected it and it's a Realtek with this id string: pci\ven_10EC&DEV_8136&SUBSYS_C680144D&REV_05

I looked a bit but found no drivers yet.. I suppose I'll have to search harder.

ms windows + samsung = simple stuff made impossible..
