Winnt 6.0 Bootmgr

[os2fan2]

Here is some testing-results i got from testing Winnt 6.00.5112 bootmgr with other Windows.

Adding the switch /USENEWLOADER places the program in the front menu.

The new bootmgr requires you have the file %WINDIR%\SYSTEM32\WINLOAD.EXE in the target operating system. You can use the one supplied with lockcorn (zb. nt 6.00.5112). Note this does not work with 4.0 or 5.0 versions.

Windows 4.00.1381 sp6 must be booted from the "legacy" menu.

Windows 5.00.2195 sp4 must be booted from the "legacy" menu

Windows 5.10.2600 sp1 can be booted from the main menu or legacy menu. The file %windir%\system32\winload.exe must be copied from lockcorn to 2600 to work. [isn't it wonderful that the last big use of 2600 was Atari 2600! ]

Windows 5.20.3790 svr or x64 are not tested here

Windows 6.00.5112 must be booted from the main menu. [The beta version of Neptune that circulates is build 5111. Point upgrade?]

Windows leghorn uses a new boot sector. If you want to completely eliminate this, it is reccomended to have a c:\ as fat, and a DOS boot disk. Then use the latest version of bootpart.exe [from http://www.winimage.com/ ], and the versions of NTLDR and NTDETECT.COM from Windows 5.20 or earlier. A backed up version of BOOT.INI is handy, but not essential.

Restore the WINNT boot sector, and copy the NTLDR and NTDETECT.COM to the hard disk. c:\. Edit the boot.ini file to remove traces of /USENEWLOADER switch. Leghorn is then uninstalled.

4.0 will crash if either kdcom.dll or winload.exe are in system32

5.0 will boot if winload.exe is present, but only if the boot is from the 'legacy' menu.

5.1 requires the winload.exe file, and will boot from both the bootmgr and legacy menus.

6.0 will only boot from the bootmgr menu.

Looks time consuming, but props none-the-less for posting this info...i will probably print this for future reference anyhow... B)

I put leghorn on a box that already has all of these.

Lockcorn will still put boot-sector loads (like Windows 95, MS-DOS, and Linux), on the front menu.

Note that both the front and back menus are derived from boot.ini, and entries that have an rdisk() notation, and no /USENEWLOADER switch will be under the legacy menu (along with everything else!)

More on lockhorn and co.

If you have a messed up ntldr / ntdetect.com [ie from different versions of Windows], the leghorn install will bluescreen with a 'corrupt disk' message.

i currently have on the testbox 4.00.1381 sp6 and 5.20.3790 sp0

5.20.3790 boots with no trouble, when you try the winload.exe + /USENEWLOADER trick.

Win98 appears in the front menu, presumably, it is stabler than Windows XP.

[it is purely a commercial decision that Windows XP can be booted using the old boot system, without having to go through a different menu. It could have easily been achieved by using \boot\ntldr and \boot\ntdetect.com without having to go through all the rigmoral of having to select from the legacy menu].
