[SOLVED] LILO config , dual boot and mounting a cdrom

first post !

appreciate the help in advance,

Current setup includes slackware 13 64 bit, running off an hp hdx16 laptop. In the process of setting up a dual boot scenario with a previously installed version of Windows 7.

In my attempt to copy a 512-bs .BIN image of my LILO Configuration on /dev/sda4, I am under the impression I must first copy that .bin file to media recognizable by Windows and install it in it's /dev/sda1 boot partition, before configuring bcdedit.

My setup appears as follows :
# fdisk -l

/dev/sda1 * 1 13 (Blocks: 102400) Id (7) System (HPFS/NTFS)
^ under the impression this is a boot partition created by the Windows 7 installation initially. fdisk -l states :
Partition 1 does not end on cylinder boundary.
/dev/sda2 13 50998 (Blocks: 409533440) Id (7) System (HPDS/NTFS)
^ Windows 7 partition
/dev/sda3 50998 51520 (Blocks: 4197536) Id(82) System (Linux Swap)
^ Linux Swap
/dev/sda4 51521 60801 (Blocks: 74549632+) Id(83) System (Linux)
^ Slackware partition , LILO is installed here @ the root position.

I've run the following command to copy the first sector of my Linux partition to a .bin file, using : dd if=/dev/sda4 of=/tmp/linux.bin bs=512 count=1

# dmesg | grep 'scsi' reveals:

sd 0:0:0:0 Attached scsi generic sg0 type 0
sd 1:0:0:0 Attached scsi generic sg1 type 5

# dmesg | grep 'hd' reveals:

Registered led device: hp::hddprotect

Another I ran into was, setting the default boot flag to /dev/sda4 via fdisk, runs fine, configuring /etc/lilo.conf to recognize the Windows boot entry as either on /dev/sda1 or /dev/sda2 results in : BOOTMGR not found * Use CTRL-ALT-DEL to reboot. What gives ?


Edit :

Still working on the LILO booting Windows 7 boot partition properly. Continuously getting BOOTMGR missing. What I've learned however, is that on Windows 7 Ultimate, this "100 MB" partition handles Bitlocker encryption, the bootloader and WinRE (the basic files for recovering Windows 7). Unfortunately, it does not seem that LILO is able to boot such a partition. So it looks like I must resort to having BCDEDIT (the default boot loader for Windows) handle the situation.

Should assist most people experiencing similar errors/situations.

All the best.

Hi, welcome to LQ!


From your post it's not quite clear to me what you're trying to
achieve with the bin file from sda4 ...


I never tried to set-up Win7 in a dual-boot environment, but with
older versions of windows what you normally do it to put lilo in
the MBR of the device, and choose the OS from there.

A minimalistic lilo.conf that should work for you would be something
like:

# Start LILO global section
# Append any additional kernel parameters:
append=" vt.default_utf8=0"
boot = /dev/sda

default = Linux

# Linux bootable partition config begins
image = /boot/vmlinuz
  root = /dev/sda4
  label = Linux
  read-only
# Linux bootable partition config ends
# Windows bootable partition config begins
other=/dev/sda1
  label=Win7
  boot-as=0x80    # must be C:
# Windows bootable partition config ends

Cheers,
