HI I have a HP Pavilion dm3. It came up with a BSOD and then didn't give me an option to start up in safe mode.

I dont have any cd drive, nor did it come with a Windows cd anyway. I presume that it has a partition in my laptop for that kinda stuff. I was hoping to boot it using a usb but I don't know how to do it or where to download the stuff from. I have access to network computers, so am able to download from the internet but it's not a Windows7 computer.

I am able to download from the computers that I have access to, but unable to run any executable files on them.

Can someone please help? Thanks in advance

First of all, you need a USB thumb drive. I think 8 GB is enough.

Please go and download Rufus which is very easy to use and lightweight. You can create a bootable device with the ISO image you have. But I think you have to do this on other computers.

Restart your computer. Change your BIOS boot order. You have to choose USB Device and save the settings. Then, there you go. Hope it helps. (Welcome to SuperUser)

Thanks. But where do i get the iso image from - does it have to be from a windows7 computer or can any network computer do? If any network computer is fine, how do I get it anyway? –  Lee Dec 13 '12 at 3:48
    
You can get some ISO here ( mydigitallife.info/… ) but you already must have a license key or have to purchase. –  Ye Lin Aung Dec 13 '12 at 3:51
    
I suspect that is the product key at the bottom of my laptop with pretty scruffed numbers and letters. Will try to see if I can still obtain the numbers. How do I know which Windows 7 I am on? Thanks –  Lee Dec 13 '12 at 3:53
    
It's likely to be Windows 7 Home Premium x86 (32-bit) and Yes, you can try the product key you have. Else, if it's still under warranty, you should try calling HP. –  Ye Lin Aung Dec 13 '12 at 3:57
    
thanks. I have now copy the ISO file plus the rufus.exe onto a usb drive. Can I just put the usb into my laptop and try to change the bios settings? –  Lee Dec 13 '12 at 3:58
