Tip & How-To about Computers & Internet

Unable to start Windows

Before we start, always check there are no USB devices/drives attached, or any discs in the cd/dvd drive.
If there are, remove them and try to boot....
Still no windows?......Read on

Depending whether you have a recovery disc, or a full version of windows, you still may be able to repair your installation.
If you have a recovery disc, and you can use it, you will restore your computer to factory fresh state, you will loose all your files/programs. (If you wish to do this you may want to save your files, to do this follow the "LIVE" linux install option (bottom of page)
If you have a windows disc (the same copy as you have installed on your computer), try this....BASED ON WINDOWS XP, JUST GOOGLE WINDOWS REAPAIR INSTALLATION + VISTA OR WINDOWS 7 FOR INSTRUCTIONS ON THOSE OS'S

  1. Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive. Check your system documentation for steps to access the BIOS and change the boot order.
  2. When you see the "Welcome To Setup" screen, you will see the options below This portion of the Setup program prepares Microsoft
    Windows XP to run on your computer:

    To setup Windows XP now, press ENTER.

    To repair a Windows XP installation using Recovery Console, press R.

    To quit Setup without installing Windows XP, press F3.
  3. Press Enter to start the Windows Setup. do not choose "To repair a Windows XP installation using the Recovery Console, press R", (you Do Not want to load Recovery Console). I repeat, do not choose "To repair a Windows XP installation using the Recovery Console, press R".
  4. Accept the License Agreement and Windows will search for existing Windows installations.
  5. Select the XP installation you want to repair from the list and press R to start the repair. If Repair is not one of the options, END setup. If repair is available.....
  6. Setup will copy the necessary files to the hard drive and reboot. Do not press any key to boot from CD when the message appears. Setup will continue as if it were doing a clean install, but your applications and settings will remain intact
IF the repair option is not available, and you continue to load windows, you will loose everything.

LIVE LINUX INSTALL (google "live linux distro")
IF you want to save files/documents before a recovery or clean windows install, you can download various " LIVE" Linux distrabutions.
You Burn these to a cd as a bootable ISO file ( imgburn is a free burning program that will enable you to make bootable ISO discs).
Some linux distrabutions have built in recovery tools/virus scanners.
Once you have recovered your important files, you can either carry on with the windows recovery, clean install.... OR...you may find that you like LInux, if so you can fully install the linux OS and if its not what you want, Install Windows back in.

After installation dont forget .......
1.Download and install your security programs (Anti-virus/Anti-malware)
2. download drivers from your manufacturers support page
3. turn automatic updates on

NOTE............When you are up and running, and want to transfer any saved files you may have recovered..SCAN THEM with your Anti-virus BEFORE you put them onto your nice clean PC.
All of this information is available freely on the internet, just google your relavent question.

My ABIT sg-72 motherboard boot attempt from HDD says "NTLDR is missing". The only Enabled boot device is HDD. If I change boot device in setup to CD (Windows XP distr disk), that boots up and runs Windows XP Pro properly. I also copied NTLDR and NTDETECT.CMD from the CD and then rebooted, but I get the same error message.

dvd/cd is not working


You can follow these methods to try to isolate and resolve the problem. Use these methods in the order in which they are presented.

Method 1: Clean the disc

When you have problems with a CD or DVD drive, always check the disc first to see whether it is damaged or dirty. To clean the disc, follow these steps:

1. Remove the disc from the drive.
2. Clean the disc with a disc cleaning kit or by gently wiping the silver side of the disc from the center outward with a dry, soft, lint-free, cotton cloth.

Note Do not use a paper cloth, and do not use a circular motion to clean the disc. These can scratch the disc.
3. Reinsert the disc in the CD or DVD drive.
If the computer can read the disc, you are finished.
If the computer still cannot read the disc, go to step 4.
4. Try again to clean the disc by using a cloth dampened with water, or dampened with a commercial CD or DVD cleaning solution.
5. Dry the disc thoroughly, and then reinsert it in the CD or DVD drive.
6. If the computer can read the disc, you are finished.
If the computer still cannot read the disc, go to method 2.

Method 2: Check the disc for damage

If the disc is clean, check whether it is damaged. To do this, follow these steps:

1. Remove the disc from the drive, and then examine the disc for scratches or cracks.
2. If the disc is damaged, try another disc to see whether the CD or DVD drive can read it.
3. If the computer still cannot read a disc, there may be a problem with the drive. Go to method 3 to troubleshoot the CD or DVD drive.
If the computer can read the other disc, there is a problem with original CD or DVD. Contact the manufacturer of the damaged disc to obtain a replacement.

Method 3: Try a different disc drive

If the disc is clean and undamaged, check whether there is a problem with the drive. To do this, follow these steps:

1. If the computer has more than one disc drive, insert the disc in a different CD or DVD drive to see whether it can read the disc.
If your computer does not have more than one disc drive, you can insert the disc in a different computer.
2. If the other CD or DVD drive can read the disc, there may be a problem with your CD or DVD drive. Go to method 5.
If the other CD or DVD drive cannot read the disc, the disc may not be compatible with the drive. Go to method 4.

Method 4: Make sure that the disc is compatible with the drive

Check the following list to make sure that the disc that you are trying to use is compatible with your CD or DVD drive.

* A DVD disc is incompatible with a standard CD drive.
* A CD-RW disc is incompatible with a CD drive that does not support CD-RW discs.
* A DVD disc is incompatible with a drive that does not have a DVD logo on the front.

If the disc is compatible, go to method 5.
If the disc is incompatible, use a compatible disc or contact the vendor for a compatible replacement.

Method 5: Use Windows Update to check for updated drivers
If the disc is compatible with your CD or DVD drive, check for updated drivers that the CD or DVD drive may be missing.

Good luck
