Slow and buggy BIOSes
- E2B warns of a BAD BIOS during booting (e.g. EeePC booting from large >137GB USB HDD)
- E2B menu loads but some payload files do not run correctly
- A Windows Install Flash drive prepared using Rufus or the Microsoft USB Tool gives a BSOD and won't boot to the Setup screen
- You get a 'Missing MBR Helper' boot error message (to fix - reformat using RMPrepUSB. If using .imgPTN files, rename to .imgPTNLBAa)
- Very slow to get to the Main Menu
- Works fine on a different system or if booting via RMPrepUSB+QEMU or Virtual Box
To fix these issues
Grub4dos version 0.4.6a includes a built-in Grub4dos USB 2.0 driver which may fix these issues because the BIOS USB driver code will not be used (hold down SHIFT key as E2B starts to boot to load USB 2.0 driver).
- You can then install the USB driver using the Install fast Grub4DOS USB 2.0 Driver in the Utilities menu entry.
- Now you can try your ISO or payload menu entry again to see if it now works correctly.
Possible ways to try to make your E2B drive boot on a wider variety of systems
a. Install Grub4dos to the MBR and the PBR using RMPrepUSB (this installs a special version of grub4dos which is more reliable)- do NOT update the \grldr file.
b. If you are using a USB Flash drive, ensure it has two partitions - you can use EaseUS Home Partition Master to create a very small hidden partition at the end of the drive (any size or type will work).
c. Ensure that \grldr is the same version of grub4dos that is included in the E2B download.
If your (Dell) system only boots from a USB Flash drive (not a USB HDD)
clearpause --wait=3 Booting from Easy2Boot USB Helper Flash Drive...find --set-root /_ISO/e2b/grub/menu.lstchainloader /grldrbootNote: This file is probably already present on your Helper drive.
If your Gigabyte system just hangs (no grub4dos boot)
Fujitsu/MSI does not CSM boot
MSI mainboards - Look for a 'Windows 8' or 'Microsoft OS' option in the BIOS and disable it (see below).
If Windows Vista/7/8 will not install ('system partition' error)
Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information.
Windows is unable to find a system volume which meets its criteria for installation.
then ensure that the BIOS boot order is set so that the internal hard disk is the first boot device. Do not set the USB Hard disk as the first boot device.
Using Vista/7/8 Installs from a USB Hard drive without a Helper drive
Note: Windows Installer CDs/DVDs (Vista and later versions) can also be installed by using a partition image file (.imgPTN file) made from the ISO by using MakePartImage. You can then boot from this image file in either normal BIOS/MBR mode or UEFI mode if you have a UEFI system. Booting these Windows Installers using a partition image also avoids the need for a Helper USB Flash drive. See here for details.
No UEFI-boot option on some UEFI-systems
No CSM\Legacy\MBR boot option
- Set a BIOS Administrator password
- Disable Fast Boot
- Disable Secure Boot
- Enable any CSM or Legacy or MBR boot option
- Disable an 'Windows 8' or 'Microsoft' boot option
