10 It may be better to use the /export function to back up the BCD file.

25 I can't see in there your MSWindows Boot Manager entry. This BCD will not be
26 able to boot MSWindows natively, or chainload Linux from it ... you'll need to
27 repair it with your Vista CD as I suggested in the previous message.

38 I suspect that's not enough to load the boot manager. Compare it to my entry:

64 That's good, but I suspect it won't work because your Boot Manager entry is
65 not correct.
66
67 > After reboot it reverts to the original - just as well, because the

70 Yes, it looks dodgy to me too. If it reverts to the original then that means
71 that you are not actually editing the BCD file that is being used for booting.
72 I suspect that what's happening here is that Acronis OSS has taken over the
73 MBR and the boot files (I think it saves them in a BOOTWIZ folder or something
74 similar). So the BCD file you are editing is not the one Acronis is using.
75 My method implies that you have restored your Vista to its original state as
76 far as MBR and MSWindows boot files are concerned. So, for it to work you
77 will need to uninstal Acronis OSS I'm afraid and repair the start up files as
78 I described in my previous email.
79
80 Alternatively, you may want to try using bcdedit to edit the correct BCD file,
81 *but* I am not sure that Acronis will allow you to do that (it probably
82 altered the access rights to it, that's why a reboot shows up the original
83 file).
