Windows wont start. dont know how it happened.

Sounds like the image doesn't have the right drive controller driver included. Could be because the image was created on a different laptop or could be the drive controller is configured differently. You can confirm this from the STOP error code on the blue screen

Go into the BIOS setup (probably F2 at boot) and see if the controller mode is set to AHCI. If so, set it to compatibility or combined(?) and try again.

Either way, if you've installed an image for the wrong hardware, you probably should do a remedial install. Boot from your Windows XP disc and follow the prompts as if you were doing a clean install until you get to the license agreement. At the next screen, it should show you any existing Windows installs and give you a new option to repair. Let this go - it won't touch any user files, just replace all the Windows files with those from the CD. Have your system drivers and service packs handy to tidy up when it's done.

Well you can reset your windows 7 password to log on the windows with the newly created password. And so many methods can help you ,such as the easiest way is use Windows Password Reset, or reset in safe mode ect.

Head over to the Dell download center.
Just click the little arrow next to Video, then click the blue download button in the ATI-Driver field.

Your Operating system (Windows etc) is corrupt or missing. You have to get it reinstalled. There can be other reasons which can be determined after proper trouble shooting.

To get in to bios you have to reboot and once screen turns black keep on pressing F2 key but dont hold it down but tap it and it will bring you in to bios menu. Some dell's use "Del" (delete) key so if this is the case just do same thing instead of tapping F2 just keep on tapping "Del" key. This will take you into bios. If this daris nuke does not work just put in your windows cd and reboot and on black screen just keep on tapping key F12 and this will ether give you boot menu to choose form and you need to choose cd or dvd rom or sometimes it will go in to it right away and it will say "press any key to boot from a cd-rom" so you can press any key on keyboard (like space bar) and then choose option to install windows and not repair, choose delete partition which is usually like couple screens(one is letter L and one is just delete) and then choose install windows and choose quick or normal format. Once formatting is done it will start the new install. Good luck.

press F2 to go to the system setup, then press arrow down to highlight Standard CMOS feature, then press enter. Verify if the hard drive is detected, mostly it is installed in SATA 0 and you should see like a serial no of the Hard drive. If the hard drive is not detected, you might need to reseat the cables of the hard drive inside the computer. Make sure that all the cables at the back of computer is unplugged to be safe. After you reseat the hard drive cable, plug cables at the back of the computer then turn on computer and press F2, verify if the hard drive is detected, if still not, try to swap the connection of the hard drive and the dvd drive of the computer. Plug back the cables and turn on comp and press again F2, this time the the dvd drive should be on the SATA 0 and hard drive should be on the oter SATA port. If the hard drive is still not detected, you need to replace the hard drive, but if the hard drive is detected on the other SATA port and the dvd drive is not detected on SATA 0 then you need to replace the mother board.

1. Backup all your documents and files that you like to use after format.
2. Insert your windows bootable cd and enable/turn first booting from cd-rom from BIOS setup (usually when you press del or F2 on computer starting).
3. After restart computer asks to press any key to boot from windows cd.
4. Then you get blue screen with lot of funny text you can read all that if you like or press next then choose format drive c: NTFS and follow instructions.
5. After installation you get nice clean desktop without these annoying icons. First thing you may like to do is install all missing drivers. If you dont have original drivers cd then you can download them from dell support site you may backup network drivers to usb memorystick before format if you dont have original drivers cd.

6. Have fun :)

the BIOS is hard wired into the motherboard and contains all information about the hardware on M/board.usually accessed by pressing del key or f2 key you will have how to do this at the bottom of the boot up screen read all info carefully it should list what your hard drive is and how big
also if hard drive is automatically detected
if you access it set it for default loadings and try again to boot

when u start the pc
Goto bios setup bu pressing F2, DEL or TAB which ever is applicable to ur system
When u reach the bios setup screen
There would be an option to Disable all passwords
Just enable the option and restart ur system
It will not ask u for a password
