Default MBR switch on FDISK

Oops. I was too quick to post that quote of...
http://support.microsoft.com/default...41&Product=w98
....It wouldn't be a "MS-DOS 6.x Upgrade Setup Disk 1" for you, but JUST
a regular Startup Diskette.

(1) Perhaps yours is bad, if it will not see partitions. Then...
Get a Startup Diskette from
http://www.bootdisk.com/ , if you don't already have one from "Control
Panel, Add/Remove Programs, Startup Disk tab". Test the Startup
Diskette. Boot it, put in a CD and "DIR" the CD. It will say which
letter is the CD. (Otherwise, it is likely one letter higher than
normal.)

(2) Perhaps your partition are not the "type" that are recognizable by
DOS. Then, you must wait for Blanton to arrive. (I still haven't
assimilated it.) Does Partition Magic allow you to change the partition
"type". NATURALLY, all one may safely do is to change it from a hidden
type to it's proper unhidden form. One may NOT simply convert an NTFS to
a FAT32, for example, by changing type!

| That's what I was trying to say: although the PM 'Recovery Disk'
| (mainly a
| boot disk with PM on it) shows the partitions on both disks as present
and
| with no problems, the boot disk DOS can't see them--not even C:\--even
| though if you don't use the boot disk, it's clearly using the C drive
to get
| the message: 'Type the name of the Command Interpreter....' as I
described
| previously.
| I think this may go back to a thread back in April, or March, in
which
| you and cquirke and several other people got involved, but then it was
a
| question of Restarting in DOS Mode. Although I finally thought that I
had
| the
| answer in the question of the receipt of the Windows shutdown
broadcast (and
| the answer may still lie there) I was never able to fix it, and other
things
| (the machine I'm using now) came to the fore. Unfortunately, I only
| archived a few of the posts, and I was using the MS support interface
at the
| time. The server doesn't seem to have retained any posts prior to the
| beginning of May, so I can't find the thread there, and it probably
wouldn't
| do much good, since I doubt I could convince anyone that the two are
| related. Would take even longer to explain why I think so, and it's
| irrelevant, if the thread's not available.
| Obviously, this rambling reflects the state of my understanding,
but it
| comes down to: If PM can see the disks and the partitions, (1) why
can't a
| boot disk see any of them, and (2) how does one access anything on the
disk
| if the boot disk can't see it. Along the way, I might mention that
this is
| an installation without any older DOS on it, so that it would be
deadly to
| overwrite IO.SYS with a DOS 6.22 IO.SYS. Any of the files would have
to
| come off the W98SE installation disk, and that's a little difficult as
it
| stands. I certainly don't want to reformat the disk.

| Thanks,

| Err Msg: The Following File Is Missing or Corrupt...
| (187641) - When you start your computer, you may receive the
following
| error message: The following file is missing or corrupt:
COMMAND.COM.
| Type the name of the Command Interpreter.
|
| It says...
| ......Quote article...................
| RESOLUTION
| To resolve this problem, use the MS-DOS 6.x Upgrade Setup Disk 1 to
| restart your computer, and then use the SYS command on drive C. To
do
| so, follow these steps:
|
| 1. Place the MS-DOS 6.x Upgrade Setup Disk 1 in drive A, and then
| restart your computer.
| 2. Press the F3 key when MS-DOS Setup starts to exit MS-DOS Setup.
| 3. Type sys c:, and then press ENTER.
| 4. Restart your computer.
| ......End of quote....................
|
| HOWEVER... here are some warnings...
|
| This will copy certain system files (IO.sys, Command.com & perhaps
| MSDOS.sys) from the Startup Diskette to C:\. (It also sets the BPB
drive
| number to HD0, so that it is now in the bootstrap. It does so, no
matter
| whether it is HD0. To boot it, one must still move it to be HD0,
| however.) You may now be able to boot to Windows, if all folders are
| intact. If not, some further adjustment need be done to "MSDOS.sys",
| that was copied to C:\. The floppy has just a shell of it. Well,
remove
| the floppy & boot.
|
| Oh gosh! Here are some warnings from Jeff Richards, MS MVP W95/W98,
| about "SYS C:". DON'T DO IT, he says, if:
|
| (a) "Major errors were reported in Scandisk."
| (b) "A drive is moved from one machine to another", because of the
next
| two, maybe.
| (c) "The BIOS setting for a drive is changed (eg, LBA to LARGE)."
| (d) "A drive that uses overlay software is operated without the
overlay
| loaded."

| | Yes that was what I was recalling something about--as I said
to
| Curt,
| | all my refs went down with that machine.
| | The problem here is that this is wierd--it's clear that the
boot
| code
| | is working to some degree--'Starting Windows 98' comes up first,
which
| it
| | normally wouldn't show, then it comes up with 'Type the name of
the
| Command
| | Interpreter (e.g. C:\WINDOWS\COMMAND.COM)' cr'A' even though
| there's no
| | disk, boot or otherwise in the floppy drive. Also, putting in the
| startup
| | disk doesn't get me anywhere--after choosing boot without cd-rom,
to
| | simplify it, it just hangs with the floppy drive trying to access
| something.
| | But it seems that this must be coming from IO.SYS, since there
| couldn't be
| | much else doing it, if no COMMAND.COM has been loaded (of
course..who
| | knows..).
| | I should mention that this started with an *apparent* CMOS
| failure--a
| | little strange since I just replaced it with a new Li cell just a
year
| and a
| | month ago. Nothing very strange seemed to have happened to it,
except
| all
| | the drives (floppies, too) had been lost, and this was on the
first
| boot of
| | the day.
| | I reset the boot order for it to boot A: first (had been C:
then
| A and
| | was able then to boot to DOS from the startup disk, but could not
see
| the
| | other drives (just A. I had previously installed an old version
| (4.0) of
| | Partition Magic and used the PM recovery disk to find out that the
| | partitions were all still there--but this version doesn't do
anything
| for
| | MBRs, apparently.
| | In short, the EOS byte could easily be missing, AFAIK, and the
| only
| | thing I can see at the moment is to use Debug to see if it's still
| there.
| | Clearly, I would welcome any thoughts on the subject before I
try
| | anything. I'm a little leery of slaving the disk to my other
machine,
| if I
| | don't know for sure what caused the problem.

| | Thanks for your time,

| | Enter "FDISK /MBR"
| | This will rewrite the code portion of the Master Boot
Record,
| | leaving the Partition Table untouched, except it may muss the
| partition
| | table, if there is a missing End-Of-Sector marker (55AA), per
| |
http://support.microsoft.com/?kbid=149877
| | Boot Record Signature AA55 Not Found
| |
| | Here are the warnings against it...
| |
| | (a) If you have a boot sector virus, you may lose access to all
| | partitions. Then
| | http://www.terabyteunlimited.com/utilities.html MBRWork "might"
help
| to
| | recover them.
| |
| | (b) If you have "overlay" code in the MBR, e.g., EZ-BIOS,
Maxblast,
| a
| | boot manager, then that will need to be reestablished
afterwards.
| | http://www.aefdisk.com/ FDISK & Boot Manager
| | http://support.microsoft.com/support.../Q245/1/62.ASP
| Overlay
| | Utility & FDISK
| |
| | (c) FDISK may be buggy. So? Use MBRWork to do it, or
| | http://support.microsoft.com/default...;en-us;Q263044
| | Latest FDISK, hoping this one doesn't have any bugs. (But it
doesn't
| | solve the 55AA thing.)
| |
| | (d) If for some reason the "geometry" setting in BIOS does not
match
| the
| | hard drive, then any write to the drive may be destructive. So,
go
| into
| | BIOS and have it "automatically detect" the proper setting. (If
you
| can
| | DIR the drive in DOS, then you have proven the geometry is
right.
| Well,
| | Blanton says even that may not be true.)

| | | I think I recall reading someone posting that the /MBR
switch
| on
| | FDISK
| | | not only rewrites the master boot record, but also wipes out
| partition
| | table
| | | data, so that if you use /MBR on a disk with multiple
partitions
| on
| | it, you
| | | lose the partition data. Is this true?
| | | I have a problem with a corrupted MBR (I think) and my old
| version
| | of
| | | Partition Magic doesn't do the MBR, apparently.
| | | Thanks for your time, as always,
