CD/DVD/Blu-ray drive/writer problem: Can't copy files to an external DVD writer because the computer can only start in Safe Mode

My desktop PC runs Windows XP Home Edition fully updated to Service Pack 3 (SP3) plus all of the subsequent security updates. It will only boot into Safe Mode and shows vertical lines on the screen. I think that it's on the way out, so I want to copy my many files to DVD-R discs on my external USB DVD writer and then transfer them to my other computer. The problem is that I can't access the USB DVD writer from Safe Mode. Is there a way out of this situation?

Answer

If the computer works in Safe Mode (you can run malware scanners, defragment the hard drive, etc.) then the problem is almost certainly software, not hardware-related, and is probably a problem with Windows itself.

You need Windows XP (or Windows Vista or Windows 7) to be running in order to be able to access USB devices, because the device drivers have to be loaded before they can function, and they aren't loaded by Safe Mode. Therefore, backups made to an external USB device are not usually of much use when Windows XP or Windows Vista/Windows 7 aren't working. However, there are several possible ways to solve your problem.

The first action you should take is to try using System Restore from Safe Mode to restore a restore point that predates the problem.

I take it that the PC also has a standard internal CD/DVD drive installed.

If using System Restore doesn't work (sometimes it simply won't work), then try performing a repair installation (of Windows XP).

A repair installation, which installs over the existing installation, is an effective way of repairing damaged or corrupt files and settings, because it leaves all of the programs and preference settings intact. The Windows Registry isn't replaced by a new version that has no knowledge of the installed programs, so they don't have to be reinstalled. As with reinstalling Windows XP over itself, detailed next, you have to reinstall any missing service packs, fixes and updates. How to perform a repair installation of Windows XP is detailed here on this website:

This page on this website provides information on repairing an installation of Windows Vista: http://www.pcbuyerbeware.co.uk/...

This page on this website provides information on repairing an installation of Windows 7:

Reinstalling Windows XP over itself without formatting the C: (usually the boot drive) drive first is the next option you should try to get Windows itself operating in normal mode if restoring a restore point in System Restore and a repair installation failed to work.

It is possible to recover Windows XP just by reinstalling it over itself by running its setup program on its installation CD. None of the settings are lost, the files and folders remain intact, and you can use all of your programs and your Internet connection, etc. However, you will have to reinstall all of the missing service packs (SP1, SP2, SP3) and updates that Automatic Updates (accessed in the Control Panel) installed.

For example, if you have a Windows XP SP2 installation disc, you will have to reinstall Service Pack 3 (SP3) and all of the subsequent fixes and security updates. Service Pack 2 (SP2) incorporates SP1, so you don't have to install SP1 first, just install SP2. The SP3 update will update a Windows XP Service Pack 1 installation and a Windows XP Service Pack 2 installation. Windows XP SP3 aggregates all of the previously-released XP fixes, but Microsoft says that at least SP1 has to be installed on a system running the original release of Windows XP before installing SP3. It recommends installing SP2 first as well to the original 2001 release, but that is not a strict requirement.

At the time of writing (July 2010) Windows Vista had two service packs (SP1 and SP2) and Windows 7 was expecting its first service pack in September 2010. You can use the Google search box at the top of this page (enable the Web Search option on the first search page) to find out the equivalent order of the installation of the service packs for Windows Vista.

You can check this for yourself after you have reinstalled Windows XP over itself by opening Add or Remove Programs in the Control Panel. You must have the Show updates option enabled. To do that, if the PC's BIOS supports booting from a CD/DVD drive, you must set it (in the BIOS) as the first boot drive, boot from the Windows XP installation CD, and follow the setup procedure that unfolds automatically. You cannot boot from a CD/DVD unless the CD/DVD drive is set as the first boot device in the BIOS. If there is no disc in the CD/DVD, Windows will attempt to boot from the device that is set as the second boot device.

If attempting that didn't solve the problem, check the motherboard's BIOS setup program to find out if it supports a "Boot from USB" setting for a USB CD/DVD drive. The settings for the CD-ROM drive boot priority (which includes CD and DVD drives) are usually on the second page of the BIOS, which is usually called something like Advanced BIOS Features. The older the computer, the less likely you are to find the required setting. If the option is there, you can enable it and then try booting from the external USB drive with the Windows XP installation CD in it. If the PC supports booting from a CD/DVD disc, the Windows XP installation disc is a bootable CD.

If the "Boot from USB" option is there, but won't work with your DVD writer, consider using a cheap USB flash drive. For under £10 you can buy one that can hold an operating system such as Puppy Linux from http://www.puppyos.com/, which can be used to boot the system. I purchased a 4GB SanDisk memory stick/flash drive with a retractable connector instead of a cap for £6.

If you can get the external USB CD/DVD writer to boot from a CD or DVD, you can also make use of a version of Linux that runs from a CD to rescue your files. You have to download an .iso file and burn it to a CD by making use of CD-burning software, such as Nero Express, which comes with many CD/DVD writers. You have to use its burn-image option.

Puppy Linux (and other distributions of Linux, such as Ubuntu) will allow you use the USB DVD writer, copy files, make backups, etc. Visit the Linux page on this website for more information on that free operating system).

An ideal way of recovering Windows XP would be if you could run a complete copy of it from a USB flash drive. The following free tutorial tells you how to do it.

"WinUSB is a tutorial which allows the user to run a complete Windows XP version on an USB device/stick. This tutorial is some kind of manual which you have to follow, in order to let your modified Windows XP run on your USB device. Therefor you have to regard some requirements which are also important to the avoidance of any infringement of the copyright of Microsoft. You only have to click on the tutorial menu-button in order to read more..."

"Copyright advice: The following tutorial requires a valid licensed copy of Windows XP. Microsoft does not authorize the owners of Windows XP licences to run the licensed Windows version on more than one computer at a time. The registration of Windows XP also prevents running Windows XP on multiple systems. Due to that, you are allowed to use your licensed copy of Windows XP on only one computer. That does not prevent the use of WinUSB on another computer after shutting down the first system." -
