Dual Boot Windows 7 to MS DOS

Yes, EasyBCD goes through NeoGrub to load MSDOS. What happens next?
Nothing, it's just stays at the Grub login with the TAB option.
Exactly the same thing happens to me but I am trying to dual-boot Win98SE and Win 10. Both are completely installed, but the only way I can get into Win 98 is via the startup disk and a reinstall, and the only way I can then get back into Win 10 is by running fdisk in Win 98 and making Disk 2 active again. Both OSes show up to choose from, but only Win 10 actually opens. Your programme even the latest ed. of EasyBCD 2.3 does not set in a proper path for Win 98, but I land at a curious prompt like a DOS prompt. Or else the PC complains of a missing GRUB file. Windows boot loader shows only Windows 10.

Did you install the legacy OS at the start of the HDD ?
The ability to dual boot began with XP (SP1 iirc).
MS OS's prior to that have hard-coded expectation in the OS loader that the OS resides at the very start of the HDD.
Probably not: I just took all the advice I could get, defragged my 1TB SSD and carved out 20GB formatted in FAT32. I'm not sure how to do it otherwise, unless the legacy OS had gone in first. But I do know that people are managing to put win 98 in on top of Win 7 doing nothing fancier than making space for it as I did, and then dual-boot. I am beginning to suspect that upgrading 7 to 10 before putting in 98 is the hitch. I could try starting with 7 instead in another PC (both mine are now upgraded to 10). Though perhaps subsequently upgrading to 10 may destroy the dual-boot. 10 appears to boot differently from all previous OSes. These people NIXSYS - IT for Business and Custom Build Computers and Servers offer sundry legacy arrangements at a price. But what I am after is a really powerful modern 64-bit PC with 98 on the side. I need the latter for a v. old Hebrew-Arabic-Greek DOS-based programme; and fax with distinctive ring would also come in handy, to filter out a lot of nuisance calls on my fax no.

I just installed 98 this evening, under VMware workstation 12 player.
piece of cake.
It's free for home use.
