how to start in DOS?

Question

Good evening,
while researching on the Forum, I found the following solution to resolve my issue with the Error accessing the System Registry in Windows: you need to boot into DOS and then execute scanreg /fix.
Dummy question: how do I boot into DOS? Because I tried under Windows by going to Start/Run and typing this command, but it didn't work!!!!
Thank you for your quick and kind responses.

Good evening everyone,

There are several ways to start in DOS, some more DOS than others (you didn't specify your OS; I’ll assume you have Win98); in order from least DOS to most DOS:
-1- Start/Programs/MS-DOS Prompt (this is not real DOS but DOS under Windows); type exit to return to Windows
-2- Start/Run/type command and then click OK (this is not real DOS but DOS under Windows)
-3- Start/Shutdown/Restart in MS-DOS mode (this is not real DOS but DOS under Windows); type exit to return to Windows

-4- Restart the computer; press F8 when the manufacturer's logo is displayed before the Windows Startup message appears; from the menu, choose MS-DOS Command Line; Alt-Ctrl-Del to restart in Windows
-5- Restart the computer with a boot disk and choose the DOS option
-6- Restart with a DOS disk... I did say DOS version 6.2 for example...

Options 4, 5, & 6 are booting into DOS... the first three are different and should be used in specific cases.
In your case, choose method 4 and type
SCANREG /FIX to repair your registry.

Hello everyone, just a little morning note and pfuiitt!

Ipl, I'd like to add that it is preferable under Win9x to use their "MS-DOS" (versions W95 7, W98 7.1, WMe 8) because the last "classic" DOS (ver 6.22 FAT 16) does not support the FAT 32 of Win 9x and the "large" hard drives over 2 GB.

Hello OFou,  Pfuiitt... you’re right to put a damper on my -6-! it’s only usable in very particular cases!  Have a good Sunday,  @12C4 Ipl

I add that it's not always F8, sometimes it's F4, for me it was Ctrl (when I installed W98 for a short while)

Ctrl _before_ starting windows, that is to say, at the end of the BIOS gibberish (even from the middle, it doesn’t make the machine scream)

Under the most recent Windows versions (ME, XP), it’s CTRL. Before, it was F8. You need to press it right after the BIOS POST is finished; otherwise, the operating system will load normally. If you press too early, you risk getting keyboard errors because the BIOS will think the CTRL key is stuck or defective.

Good evening everyone,  On my computers: Various Dell models running Windows 9x or W2K, both the F8 and Ctrl keys work.  However, F4 launches one of the options in the boot menu.  @12C4 Ipl

I'm on XP! I want to restore my PC and the process is done in DOS. I already have a backup on a partition of my disk. I reach the prompt c:\_ after booting my PC with a WinXP CD, but when I try to access the partition where I put my backup file, my PC says "access denied" even though I entered as an administrator! Can someone help me?

Hello everyone, for a while now I've been having a problem with my HP Pavilion laptop running XP SP1

the computer refused to let me access certain websites, especially those for antivirus, so I realized I was infected, I delayed formatting several times

until a malware software stopped installing and asked me for 50 euros to clean my system

I then wanted to proceed with a format, but fortunately my CD drive is broken, I can hear it spinning the CD, but it never finds anything, and at startup the computer doesn't boot from the CD when I ask it to, it just skips it and starts XP

I then wanted to create a bootable USB with my XP CD copied onto it, I can see the USB in Windows, I start the setup, but when I tell it to boot from the removable device, nothing happens, it boots into Windows

I also tried your F8 method to start in command prompt mode, but it always starts under XP, so when I try to type format c:, well it runs in the OS

I then created a partition E on C, in which I copied my CD

if I start the CD (.exe) from E, it launches correctly, I select formatting and restart the computer and............ still under XP

Well, I think I've tried everything, I'm frustrated, the hard drive isn't even a year old…
