I try to install a MS-DOS 6.22 on a PII 233Mhz...i created partitions on the hard drive...i boot from a floppy boot(win98)...
when i am on a: i try to launch the install in the MS-DOS 6.22 floppydisk...it is say to relaunch the computer to install ms-dos and when i restart it is say that NTLDR missing...
must i have to start from a ms-dos 6.22 bootdisk???anyone can help me?
please
thx

What're the file system and size of your harddrives? If you have FAT32/LBA/large drives/LFN(Long File Names) and/or there's no DOS present yet, then you should install MS-DOS 7.10 instead. Unlike MS-DOS 6.22 Installer, you can just launch MS-DOS 7.10 Installer from DOS command line directly.

NTLDR is not a DOS file. It is part of Windows NT/2000/XP. Did this system have one of those OSs on it previously?
Be aware that MS-DOS will alway install itself on the first partition of the fisrt hard disk it finds, regardles of what may may not have been there previously. If you had Windows NT/2000/XP on the system previously you have probably clobbered it by now.

/NTLDR is also a switch which can be used for setup of Windows 98. It tells setup not to detect previous operating systems.
Dos 6.x will not even find any drives to set up on if the file system is "above" FAT16. ie; FAT32, NTFS, etc.

before there were a DOS 6.22 and a Win 3.11 installed on it...but i formated the harddrive which i have partitioned before with fdisk...how i can know the FAT system???
fdisk create FAT 16???
or perhaps the first question about to use a large drive space in the fdisk is in cause???

also there is a rack SCSI with a FAT partition on it with files coming from a win2000 computer...you think the problem is here???

nicotito,
Please tell us what is the size of your harddrive and how many partitions are already there on your harddrive.

the hard drive have a size of 3Go and i create a partition with 2Go but at the first question in fdisk i say yes...this is not a problem???
also i must install this version of dos cause it is for production engine that was just compatible with this version...i do a foolishness cause i have to format the harddrive in the rack and i delete the partition of the principaly harddrive...i do a big error...:(

You must be using a MS-DOS 7x Bootdisk and FDISK to get Large Disk Support since MS-DOS 6.22 FDISK does not have this feature.
If you say YES to 'Large Disk Support' FDISK will prepare hardrive for FAT32! (FDISK will ask on drives greater than 256MBs)
* To install MS-DOS 6.22
You need to say NO
to keep FAT16 on larger drives.
MS-DOS 6.22 CANNOT handle FAT32.Also keep partitions at 2GB & 1GB since MS-DOS 6.22 cannot handle partitions greater than 2.1 GigaBytes

Finally found someone still versed in the archane and mystical art of DOS.
I would like to make a backup copy of my original MSDOS 6.22 disks because I know they won't last forever.
I can setup a new installation of MSDOS with the orginal disks, but any backup copies don't work.
If I try to boot to the BackupDSK1 I get the following:
NTLDR missing
If I boot to a MSDOS6.X boot disk I found on the web at www.bootdisk.com it boots to A: but when I switch to BackupDSK1 and run SETUP it starts to run program but then asks for Setup Disk #1. If I then insert the orginal MSDOS disk it runs fine.The harddrive was orginally WIN95 which I fdisked FAT16 and formated. I even tried to run fdisk /mbr from my bootdisk. No error no response.
Is there something on the orginal MSDOS disks which the setup program is looking for that isn't copied with WIN2K copy command?

I got it to work.
1. MSDOS disks must be LABELED "DISK 1", "DISK 2" and "DISK 3" The label takes up all 11 characters.
2. Second, to make the backups bootable, I transered the system files from a www.bootdisk.com boot disk to the harddrive, using sys a: c:, then to my new MSDOS6.22 backups using sys c: a:. For some reason the copies would not boot but this seemed to fix it.
