I suspect that you probably cannot, but you can name the "dummy" entry: would a completely empty one be enough to get to the BOOT.INI parsing? More generally the idea of this way to load grub4dos is that of leaving an existing MBR+PBR code untouched and keep BOOTMGR as the primary boot manager to avoid making changes to an existing working setup, if the setup isn't working (and without a \boot\BCD it won't work) there is little merit in not altering it.Īn interesting experiment would be finding out what is the bare minimum contents of the \boot\BCD, i.e. The way the Vista and 7 BOOTMGR work is that they parse first the \boot\BCD and then BOOT.INI, ignoring all arcpath entries in the latter but parsing the "direct" bootsector paths and adding them to the boot choices already found in the \boot\BCD, so yes, a \boot\BCD is most probably needed, or, if you prefer, the BOOTMGR freaks out if it doesn't find one long before attempting to parse the BOOT.INI. If it isn't (but Windows 8.1+XP is possible) then a BCD entry for NTLDR (and NTLDR) may be needed. Windows 7+ Dos is perfectly possible, is Windows 8.1+DOS? I tried just \bootmgr + \boot.ini to load C:\grldr and I got a 'BCD not found' error.?Īs long as Windows 8.1 bootmgr supports dual booting it should (I have no idea if it does). If so, does a BCD also need to be present? Post-edit: just in case, also asked here: Įdited by devnullius, 16 April 2017 - 07:57 PM. Certainly I'm not the first to want to do this? Thanks in advance! UB installs the \boot files for Linux distro to my systemdrive (which is "C:" - the FAT32 partition is ignored by Windows and I put it on "G:"). Looks old and I don't want to change my MBR - it's windows based and it should remain that way I have a small primary partition (FAT32) that is active and bootable. I was hoping there'd be a simple way out? I gave a quick look at GRUB4DOS but. If I want a second disk added, UB removes the previously installed files and begins again from scratch. I was hoping to add a bunch of recovery linux distributions to my Windows BCD Boot entries, but I quickly discovered that UB only can handle 1 linux boot entry at a time. That was great, because EasyBCD only supports Windows based iso files, not linux based. I used UNetbootin to add a working RescaLux live cd to my windows metro bootloader. Hello, I was wondering if I could use unetbootin installed on my hard drive to run miltiple linux live distributions?
