try this http://www.sevenforums.com/tutorials/681-startup-repair.html if this doesn't work see if you can acquire an iso for windows 7.

EDIT nvm that requires the disk. when you first boot your pc before it attempts to load windows a screen should flash with some function(F#) key commands, one should be for a start up or system repair often it's F11 but sometimes a different key check and press and the key at that screen, this may take a couple of tries to get the timing right.

Then you will need to redownload the iso and set up your flash drive up all over from the begining...sorry

my bios use f8 to enter anvance boot option..but mate..i even cant enter my advance boot option.it still give me an error os missing..that why i guess i just have one choice only, repair by using my window 7 bootable pendrive...do u have other method except than promp me to use dvd..

the best bet then is to find a windows 7 iso for your version and use it to reinstall. just be careful which one you grab.

yeah.i already have it,but it in my pendrive.my problem here is i cant use my bootable pendrive that contain my window 7 iso setup to repair my windows 7..that is the problem..i dont know why when i try boot via pendrive its keep saying ,'disk read error occured n press cntrl-alt-del to restart'..i already test my pendrive at my others laptop and it can boot via my pendrive..so now i know,my pendrive is ok,n i already know my bios support booting via pendrive,so now,why i still cant boot via my pendrive?

Were you ever able to boot the pendrive? Are you trying the BIOS shortcut key given on first bootup screen for Boot Menu? Flash stick may be listed as HD.

If not, then you may need to try another method to write the ISO to the stick:

Or use a DVD to boot to run Startup Repair repeatedly until Win7 starts.

Do you show the pen drive first in the boot order?

You say you were resizing your partition. Can you explain exactly what you were trying to do?

Do you have any third party bootable utilities, like GParted you could use to check your installation?
