[SOLVED] Ubuntu USB boot problem

[jaspreet.lall]

I had a dual-boot windows7 n Ubuntu 10.10

reinstalled windows...

Now when i try reinstalling Ubuntu, the USB boot is detected but is stuck...

Tried changing download sources, USBs...it is happening on all notebook computer i tried booting with it...

Please help...my netbook would die without ubuntu

So you are trying to install Ubuntu from a USB drive? Correct?
If the USB drive fails during install, it might be a corrupt download/install. Does it work on another machine?

[jaspreet.lall]

No...It does the same thing on every system i try...

I downloaded from 2 sources and still it does the same thing. From website as iso, and also as torrent.

I am a new user so dont know if i made the USB bootable right way, but it worked (2 weeks earlier) for me...

Is there any way to verify the ISO which i have...? and also to make the USB to bootable with some other software than usb-creator

If you click the links in my signature, you will find several guides that tell you how to verify the downloaded iso files.

I have installed fsum in windows...
how to go ahead with verification of the iso?

[MikeTbob]

Well, I have never used fsum but I would imagine that you start it up and point it at the downloaded iso file.

[jaspreet.lall]

thank you.
Can you please tell me the MOST successful & reliable location to download the iso from?

[MikeTbob]

I would start at the Ubuntu website and look for their mirrors page and select a location from there that is closest and offers the best speed.
