Windows 7 Installation on A completely blank hard-disk...

[Kishor0427]

So let me explain you the very big problem i am facing... I currently on Dell Inspiron 15 3541 laptop...
I had windows 8.1 Installed on it and I wanted to downgrade my os to windows 7 as the 8.1 was creating many lags in there... So I decided to clean install it through Usb flash drive... I downloaded the iso file and burnt it to usb or booted it to usb using rufus tool... Then I booted it using my usb... At the partition screen i wiped all the data and made 2 new partions but the installer said it cannot install on it due to the partition was gpt something so i searched the net for the solution they said i should convert it to mbr using command prompt.. i tried that and it didn't work... So i thought the installation nay need to restart for the change to be accepted thus I restarted the laptop but there comes the main problem my laptop didn't detect the usb drive i was using... I don't know why this happened may be because all the drivers were deleted as i formatted the whole harddisk... Then i created a dvd iso and tried using it but then I remembered that my dvd drive wasn't functioning properly... Now friends I don't know how to solve this... I am in a serious need of help... I need my laptop for an assignment please help me to solve this... Thanks in advance

1| Connect the bootable USB installer onto an available USB 2.0 port. You shouldn't be having any issues with drivers considering your platform.

2| You should boot to BIOS and make sure your primary boot device is the USB installer. Once you pass through the installation procedure, make sure to change the order to your HDD(after you have to restart for the first time).

3| Mind you, you should follow through this procedure to convert your GPT drive onto MBR. It's worked for me!
