    You guys did a good job in DD10 for converting an XP C: drive
    from 4K -> 64K clusters, and cleaned up M$'s boot mess they introduced
    at SP1A trying to make XP not boot over 4K clusters (pre SP1a boot
    blocks work to boot SP2 and later XP 64k cluster C: drives).

    Just playing around, I installed vista RC1 to a scratch drive. Then
    ran DD10 from a boot cd to convert to 64K clusters from 4K.
    As expected, DD10 "thought" it was XP and overwrote the boot
    sectors with what looked to be the XP pre-SP1a boot sectors and
    cluster aligned to start at sector 128 instead of 63. Since the
    XP boot sectors load NTLDR (vista renamed it to Bootmgr),
    this will not work directly. I then used bartPE to copy Bootmgr
    into NTLDR, and tried to boot that. Bootmgr started up ok, but
    would not load the text file C:\windows\system32\winload.exe,
    presumably, Bootmgr has something that "breaks" with 64K
    clusterso_O?
    Anybody used Grub or other means to start winload.exe on a 64k
    cluster system? M$ seems to have gone to lots of trouble
    to make XP and vista not boot 64k clusters? runs too fast
    for them?
