The Boot Manager
1. Hotkeys - Global keys
|Cursor up/down ||Move the bar
|Enter ||Choose selection
|ESC ||Close window
|CTRL - ESC ||Switch to text mode
|CTRL - PAGE UP ||Switch to higher screen resolution
|CTRL - PAGE DOWN ||Switch to lower screen resolution
|z ||Enable/Disable window zoom animation
2. Main menu
In the main menu you see all visible profiles to boot an operating system. You can start
an operating system from floppy, cd/dvd, usb or network. You can go to the setup of the boot manager,
partitions and profiles. If your bios supports APM, you can shut down your computer.
2.1. Main menu hotkeys
|1-9 ||Boot profile
|q ||Quick boot, open a list of all possible hardcoded partitions to boot
|w ||Write MBR with the profile settings, but do not boot
|f ||Boot floppy
|c ||Boot CD/DVD
|u ||Boot USB
|n ||Network boot
Special additional keys for USB boot:
Difference CTRL-u and ALT-u:
Press SHIFT-u to force USB 1.1
Press CTRL-u to wait for a key press before starting the operating system.
When a drive was found, then you can press "s" to skip the device
or you can boot from the drive.
Press ALT-u to wait for a key press before detecting the usb device type.
When a device was found, then you can press "s" to skip the device
or you can boot from the device when it's as mass storage device.
When you use CTRL-u and the boot manager finds an usb device, then the
boot manager identifies it. Because of the stripped down usb implementation,
it's possible that the boot manager sometimes hangs on some computers.
With ALT-u, the identification
of the usb drives happens when you press enter. When you press "s", then
the boot manager skips the device and it should not hang.
You can manage your partitions here. The install program creates an entry for all
primary partitions it finds. The names are from HDA1 up to
HDD4. HD means hard disk.
HDA stands for hard disk A and
is the first hard disk. The numbers 1-4 are the numbers
of the primary partitions.
Notice for linux users: HDA has nothing to do with the devices in linux like
You can change the label for the partition. This label is used in the boot manager.
The maximum length is 16 chars.
Here, you choose the hard disk of the partition.
HDA = Hard disk 1
HDB = Hard disk 2
HDC = Hard disk 3
HDD = Hard disk 4
There are 2 ways to set the ID of a partition.
1. Enter partition ID
You can enter the hexadecimal value for the partition.
2. Select ID from list
This list has the mostly used partition ID's. If the requested ID is not in the list,
then use Enter partition ID.
Edit MBR/Import data
This is used to change the values of partitions in the MBR.
BP means boot manager partition. This values are stored
in the boot manager.
P1-P4 this are the current values of the primary partitions
in the MBR.
You can edit the hexadecimal values in the partition table. You can select a
row with s (select) and paste the values to the row
where the cursor is with p. With this
function, you can import partition values to the boot manager or change values in the MBR.
This can be very useful in emergency cases.
Clear partition data
Clearing the data means clearing of the partition data in the boot manager. The data on the
partition itself is unchanged.
Use it if you changed something and you want to restore the whole values of the partition
in the boot manager. This is possible until you close the partition edit window.
Profiles are used to start different operating systems from different hard disks and partitions.
It's also possible to detect changes in the MBR made by other software and import or forget the changes.
If you have an operating system installed and you install the boot manager, the installer creates
a profile to boot the current operating system.
You can edit the label of the profile. This label is shown in the main menu. It's useful to use a
label to see what operating system is going to boot. The maximum length is 16 chars.
Show in main menu
With this option you select if the profile is shown in the main menu or not. Only visible profiles
can be booted. It also has effects on the default profile in the
boot manager setup.
You select from which hard disk, partition and bios device number you want to boot with this profile.
You can also select what partitions or cleared partitions should be used for the MBR.
Configure partition entries
There are 3 states for a partition entry
1. a selected partition
Press enter to choose a partition from a list with all partition of this hard disk
available from Partitions.
If another software changes
this entry in the MBR, the boot manager detects this change at the
next startup. You can choose if you want to import the new values or forget them.
2. don't touch
The partition entry in the MBR will not be changed from the boot manager. That is the default setting.
If a software changes this entry in the MBR the boot manager cannot detect this change.
The boot manager set's this entry to 0 in the MBR. An operating system cannot detect that there is/was
WARNING: if the boot manager has not stored the values of the partition in "Partitions" then you lose the
partition values in the MBR and you cannot access the data on the partition. It's possible to restore
those values, but it's better, easier and safe to store the values in Partitions.
Partition programs will say this is unallocated space! Do not partition this
space! You can lose data if you do it wrong.
Linked partitions - hotkeys
b set boot partition.
You select, what partition you want to boot with this profile. The boot manager set a bios drive
number automatically. It's possible to change it with another key.
c clear partition.
You set this entry to "cleared" and the boot manager clears this entry in the
MBR when you boot this profile.
d don't touch.
You set the entry to don't touch and the boot manager
does not change this entry when you boot this profile.
e edit boot flag.
The boot flag has the bios drive number used by the boot sector routine. In some cases it's required to change
r remove boot flag.
Here, you remove the boot flag from the profile.
l set logical partition.
You can set to boot from a logical partition 1-4 of an extended partition. Change the logical number by pressing "l".
L1 = first logical, L2 = second, ...
Clear profile data
You can clear the profile data in the boot manager. The data in
Partitions are not changed.
Use it if you changed something and want to restore the whole values of the profile in the boot manager.
This is possible until you close the profile edit window.
3.3. Boot manager
The boot manager has two modes to start. With the user interface menu
For the hidden mode, you have to set the boot countdown and you have
to select a default
profile. The default profile boots after the countdown.
The user cannot see that there is a boot manager in the background. If you want to
go into the boot manager, then press ESC.
You can enable and disable the countdown.
If the boot countdown is enabled, the boot manager waits the given time and starts
after the countdown the last used profile or the default profile, depending on your settings.
Edit boot countdown
Choose between 1 and 99 seconds.
Select at start
At start, the boot manager set the bar to the selected option. This works for the
hidden start mode too.
You have the following options
1. Last booted profile
2. Default profile
You can select the default profile from a list of all visible profiles.
Show floppy boot
