update : Probably it would reach sda5 but for sda5 there is missing a proper menu.lst entry .

grub4dos is shinobar's special babe and i have not even one real idea about the windows boot system .

I know there is a boot.ini that could act like menu.lst , but for the syntax i have seen some examples on the net that i could not interpret .

what this

Code:
# Windows
# this entry searches Windows on the HDD and boot it up
title Windows\nBoot up Windows if installed
errorcheck off
find --set-root --ignore-floppies --ignore-cd /bootmgr
chainloader /bootmgr
find --set-root --ignore-floppies --ignore-cd /ntldr
chainloader /ntldr
find --set-root --ignore-floppies --ignore-cd /io.sys
chainloader /io.sys
errorcheck on

is i really don't know .

I would try to boot the second Windows partition with
something like
Code:
title Windows on E drive sda5
root (hd0,4)
chainloader +1

Basta
BUT because of the drive numbering chaos it could be also
Code:
title Windows on E drive sda5
root (hd0,2)
chainloader +1

For the boundaries i want to add :

INT 13H :: 528 Mbytes (504 MiB), assuming 512 byte sectors.
INT 13H Large or Bit Shift Translation :: 8.4 Gbytes (7.8 GiB).
ATA-1 standard :: 128 GiB (≈137.4 GB), assuming 512 byte sectors
ATA-6 standard :: 128 PiB

http://en.wikipedia.org/wiki/Logical_block_addressing

It might be a good idea to try at least --force-lba options while installing bootloaders.

About missing sda3 and sda4:
AFAIK it's OK. Viktor has 1 primary partition (sda1) and one extended (sda2). Logical partitions are allways starting with no.5. Next primary partitions would be sda3 and sda4.

About copy and paste:
IIRC victor uses a touchpad. In this case there's no mddle button or mouse wheel. Pressing left and right touchpad button together does the trick.

I totally missed seeing that sda2 was an extended partition. Numbering makes since now that that fact is noted.
So use to making sda4 extended partition.

Hey everybody,

I'm still trying to cut/paste from console, but it won't let me.

Is there anything else you guys would like me to try?

Thanks!

The normal thing to do, when a new install of Puppy, will not boot, is to:
Delete install.
(If doing a full install, I would reformat the partition, just to eliminate possible file fragments hanging on. Get back to clean partition)
Reinstall Puppy.
Rerun the bootloader config program for the bootloader you use.

This eleminates one possible cause of problems. Just a bad install.

About Windows:
With Grub4dos, it puts more entries in the menu, for Windows, than you need.
This one is there by default (even if Windows is not on computer). Not sure if it ever works.
Code:
# Windows
# this entry searches Windows on the HDD and boot it up
title Windows\nBoot up Windows if installed
errorcheck off
find --set-root --ignore-floppies --ignore-cd /bootmgr
chainloader /bootmgr
find --set-root --ignore-floppies --ignore-cd /ntldr
chainloader /ntldr
find --set-root --ignore-floppies --ignore-cd /io.sys
chainloader /io.sys
errorcheck on

Quick question for all for all of you.

Is there anything special I need to do for the uninstall?

Do I have to uninstall Grub4Dos as well?

Thanks!

Grub seems to sit in the MBR . Of course you should dd if=/dev/zero of=/dev/sda bs=1 count=512 to zero the MBR and throw that old machine out of the window.Seriously grub4dos are 2 files (+MBR) : menu.lst and some *gldr* file on toplevel of sda1/C:\ which is it's Stage-2 in relation to LegacyGrub .

google is a friend :

So I uninstalled everything and deleted the menu.lst and grldr files, and not I can't boot to anything, not even WindowsXP.

Do I have to reinstall Windows again as well?

The Bootloader. EasyBCD. http://www.chip.de/downloads/EasyBCD_23603661.html

But probably grub4dos has made a mbr.12345 backup . That you can
Code:
dd if=/mnt/sda1/mbr.54321 of=/dev/sda bs=1 count=512

and would probably restore the old original MBR.

No. Boot off your Puppy CD, open a console and type
Code:
ms-sys -m -w /dev/sda

That will restore the MBR so Windows will boot again.
