Win7 Installed, Slackware64 13.0 Installed BOOTMGR is missing


Arrgghh! I discovered that I could not install Win7 64-bit in VirtualBox (because an Intel T4300 doesn't have VT-x/AMD in it, drat) so, OK, let's just install Win7 64-bit then install Slackware 13.0 64-bit and dual-boot the thing for a while.

Win7 worked fine -- got all those important security updates and all that. Installed Slackware. Works fine. Shut down Slackware, reboot, select Windows from the Lilo start-up, BOOTMGR is missing, press ctrl+alt+del to restart...

Any clues?

You can solve this easily, if you're willing to use Windows' boot manager:
  1. Boot into Slackware, change lilo.conf to put lilo on the front on the HD, rerun LILO, and reboot. You'll end up back in Windows.
  2. Install EasyBCD (http://neosmart.net/dl.php?id=1). Have it overwrite the MBR, and use it to create a boot menu with both Linux and Windows on it.

It only takes a few minutes, will work, and won't cost you any data.

I have a dual boot Windows 7 + Slackware64-13.0.

1) Format your HDD (with gparted, fdisk, cfdisk, whatever):
- Keep one partition for W7 (the installer will probably add a small boot partition in it during install and will use the remaining space as another partition for W7 itself)
- Format remaining space for Slackware as you see fit.
2) Install Slackware
3) Make Windows boot partition not bootable but Slackware's root partition bootable with fdisk or cfdisk
4) create or edit /etc/lilo.conf including:

Code:
boot=/dev/sda4 # Adapt to your layout, here sda4 is Slackware's root partition 

other = /dev/sda1 # Here sda1 is Windows' boot partition (*not* bootable)
  label = Windows
  table = /dev/sda
Should work. At least, works here

I've just finished installing Win7 (after wiping the entire drive completely clean). It created
Code:
no-name        pir/log Free Space     1.06M
sda1      boot primary ntfs         104.86M
sda2           primary ntfs       20866.87M
and left me free space of 229084.17M for installing Slackware 13.0 64-bit.

From what you suggest, I'll turn off the boot flag on sda1, leave everything else alone, install Slackware starting at sda3 with the root partition bootable.

And, with crossed fingers and toes, that ought to work.

Thanks.

So far, so good -- installed Slackware and at the initial reboot, Win7 started up, shut it down and booted Slackware and I'm in the middle of adding back man gigabytes of stuff backed-up on DVD.

All appears to be well and thank you again for your help.

[EDIT]
Callin' it good -- everything works as expected.

lilo Windows 7 boot says BOOTMGR is missing

Hi all,
Got the latest Slackware distr. and loaded it onto /dev/sdb1, Windows 7 was already on /dev/sda1 and had lilo already on /dev/sda working fine.

Now, Linux boots, but when I attempt to boot Windows 7, lilo reports "Loading Windows", then the screen shows "BOOTMGR is missing, press ctrl-alt-del to reboot". I've tried the suggestions above to no avail. I wrote lilo to /dev/sda and /dev/sdb, made /dev/sdb the first drive in the boot sequence.

lilo relevancies:

boot = /dev/sdb
change-rules
reset
# Windows bootable partition config begins
other = /dev/sda1
label = Windows
table = /dev/sda
# Windows bootable partition config ends
# Linux bootable partition config begins
image = /boot/vmlinuz
root = /dev/sdb1
label = Linux
read-only
# Linux bootable partition config ends

I did overwrite the older lilo (which would boot Windows 7) with the the lilo from the Slackware install (probably the real issue, but don't know how to fix).

All help is greatly appreciated.
