Showing boot error : USB boot

Yesterday I was trying to boot my Sony Vaio laptop by USB which already has windows 7 Home Basic. The USB containing Ubuntu 12.04 , I  made it bootable by using software pendrivelinux. I have booted it many times by using my moserbaer pendrive but this time I was using Sandisk pendrive due to unavailablity of that pendrive.

I changed the boot order in BIOS, put removeable disk at first preference. when I restarted the system was showing 'boot error'. I thought may be it is due to some fault in making pendrive bootable. and I made it bootable again, still it was showing 'boot error'.

live OS or live cd

What is live OS ?

Live OS referrs to an operating system which runs in a computer's memory instead of loading from a hard disk that mean you can directly boot your Computer System by a bootable cd or bootable removable media like external hard drive , pendrive , floppy drive etc. These live operating systems are used for temporary pupose when our installed operrating system have some problem or taking some data which is on the hard disk of a system which os has been crashed.

You can also install these Operating Systems to your hard drive also and use as permanent basis. The best thing in live os is this - You can run a live OS without an internal hard disk because it runs in Computer memory.

when the load on server is exceeded the server has less priority to assign a permanent ip it may show Identifying (.....) for some time after that Unidentified Network.
