How To Create A Boot Cd For Vista

How to create a boot disk

Updated: 12/31/2020 by Computer Hope

Note

This page provides details about creating a boot diskette, or floppy disk, for Windows and not how to create a bootable CD. If you're looking for steps for newer versions of Windows (e.g., Windows 7, 8, or 10), see: How to create a recovery disk in Windows.

A boot disk allows you to boot from a diskette instead of your hard drive. This diskette can fix issues that may arise during the lifetime of your computer or help load older MS-DOS games. Keep in mind this diskette is completely different than a restore CD or disc that may have been included with your computer.

Tip

After creating a boot diskette, it's highly recommended you write-protect the diskette to prevent any virus from infecting the disk or the disk getting erased.

Creating an MS-DOS boot disk

Note

These steps are for users who have MS-DOS installed on the computer. Find your version of Windows in the next section and follow the steps.

To create an MS-DOS diskette, begin by getting to the DOS directory by typing:

cd\dos

Once at the C:\DOS directory, skip to copying files.

Creating a Windows 3.x boot disk

Note

These steps are for users who have Windows 3.x installed on the computer.

To create a Windows 3.x diskette, from Windows Program Manager, click File and then choose the option to Exit Windows, which gets you to a prompt; at the prompt, type:

cd\dos

Once at the C:\DOS directory, skip to copying files.

Creating a Windows 95 boot disk

Note

These steps are for users who have Windows 95 installed on the computer.

In Windows 95, Microsoft has created a new method of creating a bootable recovery diskette. Unfortunately, however, this diskette does not support CD-ROM support and is missing a few recommended files. To do this, click Start, Settings, Control Panel, double-click the Add/Remove program's icon, click the startup disk, and create the disk.

Alternatively, to create a Windows 95 boot diskette manually from Windows, click Start, Shutdown, and choose the option to restart the computer in an MS-DOS prompt. At the prompt, type:

cd\windows\command

Once at the C:\DOS directory, skip to copying files.

Creating a Windows 98 and ME boot disk

Note

These steps are for users who have Windows 98 or Windows ME installed on the computer.

An excellent feature of Windows 98 and ME is its boot diskette. Using Windows to create a Windows 98 boot diskette gets all the needed boot files and CD-ROM support. To create a Windows 98 boot diskette, click Start, Settings, Control Panel, double-click the Add Remove program's icon, click the startup disk, and create the disk.

Alternatively, to create a Windows 98 boot diskette manually from Windows, click Start, Shutdown, and choose the option to restart the computer in an MS-DOS prompt. At the prompt, type:

cd\windows\command

Once at the C:\DOS directory, skip to copying files.

Copying additional files

Note

When making a boot disk, if you are running "Stacker" or some kind of a DoubleSpace or drive swapper program, this could not work.

Once in DOS and at the correct directory (mentioned earlier), you're ready to create your bootable diskette. Insert a diskette that does not contain any information since it is going to be erased.

At the prompt, if you have MS-DOS 6.2, Windows 3.x, Windows 95, Windows 98, type:

FORMAT A:/S

If you have MS-DOS 5.0 Type using double density 5.25" diskettes type:

FORMAT A: /360 /S

If you have MS-DOS 3.11 through 4.0 using double density 5.25" diskettes, type:

FORMAT A: /4 /S

Once the diskette is formatted and the system are transferred, you'll be returned to your original directory. In this directory, type:

copy format*.* a: [press Enter]
copy fdisk*.* a: [press Enter]
copy mscdex*.* a: [press Enter]
copy sys*.* a: [press Enter]
copy edit*.* a: [press Enter]
copy qbasic*.* a: [press Enter] (Win 95/98 users skip this line) copy debug*.* a: [press Enter]
copy himem*.* a: [press Enter]
copy emm386*.* a: [press Enter]

If you're planning to use this diskette as a diskette to load games or you feel that you need mouse support, you need to copy the mouse driver onto the boot diskette. The MS-DOS mouse driver is mouse.com or mouse.sys. Locate this file and copy it to your bootable diskette.

For CD-ROM support, visit our CD-ROM drivers page for information on loading your CD-ROM driver.

Once you have copied the above files, create an autoexec.bat and a config.sys. Get to the floppy drive by typing A:, once at the floppy drive, type:

copy con autoexec.bat [press Enter]
@echo off [press Enter]
LH A:\MSCDEX.EXE /D:CDROM [press Enter] (this line is used for your CD-ROM drive).
LH A:\MOUSE.* [press Enter] (skip line if you did not copy mouse file, the * is either sys or com).

Press and hold Ctrl+Z to return ^Z. Once this is displayed, press Enter to copy the file.

copy con config.sys [press Enter]
device=a:\himem.sys
dos=high,umb
device=a:\emm386.exe noems
files=30
buffers=20
devicehigh=a:\oakcdrom.sys /d:CDROM (this line is used for your CD-ROM drive).

Press and hold Ctrl+Z to return ^Z. Once this is displayed, press Enter to copy the file.

Congratulations, after completing the above steps, you have a bootable floppy diskette.

Creating a Windows NT boot disk

To create a boot diskette, you must have access to the i386 directory on your Windows NT CD or possibly your hard drive.

Format the floppy diskette you want to make a bootable Windows NT boot disk using the Windows NT machine.

Copy boot.ini, ntdetect.com, and ntldr to the floppy diskette.

If you are using any SCSI devices that you need access to, you need to also load these drivers onto the diskette.

Creating a Windows 2000 boot disk

To create a Windows 2000 Professional bootable diskette, you need four 1.44 MB diskettes and the Windows 2000 Professional CD.

Click Start, Run, browse to the CD-ROM drive.
Open the "BOOTDISK" folder and double-click makeboot.exe and click ok to launch the program to create the diskette.

Users can also create an Emergency Repair Disk by clicking Start, Programs, Accessories, System Tools, and opening backup. From the backup window, click the button for Emergency Repair Disk and follow each of the steps.

Creating a Windows XP boot disk

Note

The Microsoft Windows XP CD is a bootable CD and doesn't need a bootable floppy diskette. Booting from the Windows XP CD allows you to not only install or reinstall Windows XP, but also troubleshoot.

Create MS-DOS bootable diskette

When formatting a floppy diskette, users have the option of creating an MS-DOS startup disk, follow the steps below to do this.

Place diskette in the computer.
Open My Computer, right-click the A: drive and click Format.
In the Format window, check Create an MS-DOS startup disk.
Click Start.

Create Windows XP setup diskettes

Microsoft has phased out bootable floppy diskettes in favor of bootable CDs and has not included a method of creating a bootable floppy diskette in Windows XP or from the CD.

How to use a boot disk

Once the bootable diskette is successfully created, follow the steps below to use the boot disk.

Place the diskette into write-protect mode (in case a virus is on the computer, this prevents the virus from transfer itself onto the diskette).
Insert the diskette into the computer and reset or turn on the computer to begin the boot process.
As the computer is booting, answer the questions prompted (if any).
Once at the A:\> prompt, take the appropriate actions depending on the situation of the computer.
