It has been like a long time since no one asked questions here. I don't know if the moderator can still see and solve my problem.
The operating system I am using now is WIN2000PR + REDHAT9.0. WIN2000PRO is installed in the primary partition C drive, and the partition format is NTFS. There are also logical partitions D drive, E drive and F drive. Among them, D drive and E drive are in NTFS format, and F drive is in FAT32 format, which contains the installation files of WIN2000PRO and LINUX. It is set to FAT32 format for convenience of installation under DOS. The partitions under LINUX have a root partition and a SWAP partition, and they are all automatically set as primary partitions during the installation of LINUX. That is to say, there are already four primary partitions occupied in my current hard drive (C drive counts as one, D, E, F count as one, the root partition of LINUX counts as one, and the SWAP partition counts as one). The main boot program I use is that of WIN2000PRO, which is realized by using the dd command of LINUX and modifying the boot.ini file under WIN2000. Now I want to install a DOS, and I don't want to modify the existing MBR. This is what I think: divide a 50M G drive (which is a logical partition) from F drive (FAT32), install MSDOS7.10, then use the dd command under LINUX to make a boot record of G drive into a msdos.dos file, and then modify the boot.ini file to realize multi-boot, but there are some problems I don't understand:
First, can MSDOS7.10 be installed on a logical partition?
Second, under linux, using dd /dev/had8 /msdos.dos count=1 bs=512 and then copying msdos.dos to the C drive, and modifying the boot.ini file as c:\msdos.dos="msdos7.10", can this method be realized? (It would be better to explain in detail the process of installing and installing the boot program during the installation of MSDOS7.10)
Third, I want to use the simulation program for the computer ranking examination under MSDOS, which needs the support of UCDOS. Can it be used under MSDOS7.10?
If this method is not feasible, can the moderator provide a better plan? (My existing data does not want to be damaged)
