Can't boot Win 7 from USB ,please help me!

Hi all!

I created a bootable Win 7 USB drive with Rufus,and the USB works fine if it is opened in This PC (Win 10) ,but when I try to boot from it gives me the following error:

"Disk Boot Failure, Insert System Disk"

Please help me to fix this error and install Win 7!

P.S Before this,I had Win 10 installed on my Samsung 840 Evo SSD,but I wiped the drive with Samsung Magician.

Thanks to all in advance!
Best regards!

Hi inspiron7,



[1] What BIOS have you got, is it Legacy - MBR or UEFI - GPT?
[2] Have you got the USB as the first boot option?
[3] Where did you get the ISO to create the Win 7 installation?

I hope this helps!

First of all,thank you for replying!

1.About the BIOS, my motherboard is Foxconn G31MXP,and I can't find if the BIOS is UEFI or LEGACY


2.About the booting order,I have set the USB to first place to boot from

3.About from where I have downloaded the ISO file,I downloaded it from Microsoft

Hi inspiron7,



Have a look in Disk Management.



Good.



It could possibly be a corrupted ISO download. Can you remember where exactly?

I hope this helps!

After the wiping of the SSD ,my PC now is without OS,so I can't see in Disk Management!

I redownloaded the ISO for 2 times,but it didn't work.

Hi inspiron7,



When you formatted the SSD I assume that you deleted the Recovery Partition as well!

Yes,exactly!

Hi inspiron7,



OK.

Have you got your Product Key [On a laptop, it will either be on a sticker on the bottom, or in the battery compartment]?

NOTE: The light blue text below are links to the relevant websites and programs, just click them!

Download the latest and last Windows [Final] > Windows 7 SP1 [build 7601] > Windows 7 Ultimate SP1 ISO [build 6.1.7601 - July 2009] file from TechBench [make sure you select the correct language and bit type]. It is recommended that you download the Win 7 Ultimate SP1 ISO because all versions of Win 7 can be made available from it. This is achieved by creating a folder on the desktop and then unzipping the ISO into it using 7-Zip, and then delete the ei.cfg file in the sources folder. Alternatively, you can run the eicfg_removal_utility against the downloaded ISO. If the version of Windows you are installing is Windows 7 SP1 Ultimate, then there is NO need to remove the ei.cfg file as instructed above.

I hope this helps!

My PC is without OS at the moment!

How can I make the BOOTABLE USB to work?

Please help me!
