Edit OS Details
This screen will appear when you click the Edit or Add A New Item button on the Manage Boot Menu screen.
Menu Entry
Changes the order of the selections displayed in the Grub boot menu
Title
The text that will be displayed by Grub for this OS in the Grub boot menu selection. Must be 1 to 60 characters alphanumeric.
OS Type
When you add a new menu entry select the type of system you are installing.
Supported systems are ubuntu, suse, fedora, debian, slackware, mint, remix, android, freebsd and invaders (a Grub standalone game for BIOS systems).
When you select a supported OS, Grub2Win can generate the configuration code for you automatically.
For operating systems that Grub2Win does not support, select other.
Utility OS Types:
bootinfo Creates a menu entry for the Grub2Win Boot Time Utilities.
submenu Creates a submenu entry to allow another level of menu entries. You will need to manually create custom code for the second level menu entries.
isoboot Creates code to boot an ISO file from a disk, CD or USB drive.
reboot Sets up a menu entry to reboot your system.
shutdown A menu entry to shut down your system.
bootfirmware A menu entry to reboot to your system's EFI firmware customization (EFI systems only).
When you select isoboot or other, you will see a different screen shown here.
Change Icon
Takes you to the Change Icon screen where you can set the icon that is displayed at boot time.
OS Graphics
The graphics mode Grub will establish for the target OS when it is selected for boot.
Pause Seconds
Grub will pause for the specified number of seconds before booting the target OS. This will allow you time to read any messages from Grub, such as incorrect partition address or label name. Set to zero seconds if you don't want Grub to pause. Also sets the $reviewpause variable at boot time.
Hotkey
Use the pulldown arrow to select a hotkey character. It will be used at boot time to select a Grub menu entry. For more information about hotkeys see Hotkeys and Tablet Computers.
Windows Instance (Windows-EFI partitions only)
If you have more than one Windows installation on your computer, this allows you to set the top Windows instance. You can also change the title displayed for each Windows instance at boot time.
Automatically Generate Code (Linux, Android, Remix and FreeBSD partitions only)
Grub2Win will automatically generate the grub.cfg code for you based on the selections you make in this area. If you want to enter your own code instead, click the "I Will Enter My Own Custom Configuration Code" button and you will be taken to the Entering custom code screen.
Select Partition Address (Linux and FreeBSD only) if you want Grub to load the Linux or FreeBSD kernel from a specific partition. You must then set the correct drive and partition using the up-down arrows on the right.
Select Partition Search By Label (Linux only) if you want Grub to search for the Linux partition by it's label. Grub will then load the Linux kernel. You must then specify the Linux partition label text in the box on the right. It must be 1 to 16 characters alphanumeric. Hyphen "-" and period "." are allowed in the label text. The text must match the Linux partition label exactly for Grub to find the partition. See Setting partition labels.
Select Search By Boot Directory (Android only) if you want Grub to search for the Android boot directory by its name. Grub will then load the Android kernel. You must then specify the Android boot partition name in the box on the right. It must be 1 to 60 characters alphanumeric. Hyphen "-" and period "." are allowed in the label text. The text must match the Android boot partition name exactly. The current Android X86 default name is /android-6.0-r1. You can change the name as needed. You can also enter the directory by clicking the Select Boot Directory button.
Select Partition Search By File (FreeBSD and Remix only). This allows Grub to search and find the FreeBSD or Remix partition by the Linux kernel file name
The kernel file name must be specified in the box on the right. It must be 1 to 60 characters alphanumeric. Slash "/", hyphen "-" and period "." are allowed in the file name. The default loader file name for FreeBSD is /boot/loader.
For Remix it is /RemixOS/kernel and you can select the kernel by clicking the Select Kernel File button. The default names are filled in automatically.
Select Chainloader if you want Grub to directly boot the MBR on sector 0 of a disk drive. You must then set the drive you want to boot using the up-down arrows on the right. If you want Grub to boot the MBR of a particular partition instead of the drive MBR, click the Partition check box and set the partition using the up-down arrows.
Linux Root Device Address
For Linux only. Grub2Win displays the address Linux will probably assign to the disk and partition you have entered. At boot time, Linux may assign the address differently. This depends on the BIOS of your computer.
Special Parms For Android and Remix
This section of the edit screen will only appear on Android and Remix menu entries
32 bit will generate parms for Android or Remix 32 bit code distributions.
64 bit will generate parms for Android or Remix 64 bit code distributions. If your CPU is not 64 bit capable, this selection will be grayed out.
Nvidia Support check this box to generate parms to load the Nouveau driver for Nvidia graphics cards.
Note: You must select the proper 32 or 64 bit mode to match your distribution. Otherwise Android / Remix will not boot.
Linux Boot Parms
For Linux Android and Remix only. Grub will pass this parm to the kernel when it loads Linux.
Parms control things like video module blacklisting and the degree of detail displayed on the console. Consult the documentation of your Linux distribution for appropriate parm syntax. The standard parms supplied with Grub2Win should work for the supported Linux distributions in almost every case.
When using Chainloader boot mode, boot parms are not allowed. Since Grub does not load the kernel in this case, it cannot pass parms to the kernel.
Notes: Linux requires the nomodeset parm with many video chipsets. Otherwise Linux graphics may not initialize properly. Grub2Win includes nomodeset in the standard parms generated for Linux systems. This is done for compatibility with the widest range of video cards possible.
You may need to remove the nomodeset parm with some video chips to get the highest resolution available. Installing the latest Linux drivers for your video card may also improve resolution and picture quality. Try downloading Linux drivers from the support site at Nvidia, ATI or the chip manufacturer for your card. Experiment to get the best results.
Android and Remix may require specific boot parms to support your hardware. The standard parms should work for most common hardware. For more info on Android see the notes here: Android Notes . For more info on Remix see the notes here: Remix Notes.
Restore Standard Parms
For Linux, Remix and Android only. This button will only appear if you have modified the standard parms.
Grub2Win supplies standard Linux boot parms that work with most hardware. You may modify these parms to suit your needs. If you wish to restore the parms to standard, click this button.
