The grub2 menu system will enumerate the.grub2 files in each of the grub2 folders on the second partition and add the contents of each.grub2 file into it's own internal menu. Now, if try to go another way and install grub2 on the USB disk itself, I can't understand how to install g2hdr.bin and g2ldr.mbr to USB disk's MBR. As far as I understand grubinst utility which latest version available to me is of January 2008 contains grub(1,2) boot sectors inside it and uses these old ones. Yesterday, I had to rescue a broken Ubuntu 14.04 installation by booting from USB. Unfortunately, I was unable to get into the BIOS to change the boot order (because of a BIOS password and a bad memory.
My friend's laptop was in a car accident (he's fine!). Gta 4 unlocking code. However the laptop is very old its an Acer Aspire 1520 the CD-rom drive is broken and there is no floppy drive.
I made him a USB boot before I took a look at it and found that his BIOS cannot boot from USB. The only thing I have is a GRUB console but he is keen to just install XP (on USB) and use it just for Movies.
Is it possible using the GRUB console to get access to the USB and start the windows install? It's a tall order but I think this may be the way, or trying to install via LAN which I don't think will be achievable.

Here is a quick example of grub commands that might just work, explanations and caveats below. https://advancenew854.weebly.com/blog/nat-king-cole-unforgettable-download.
Most likely for post-2010 installs. Lastpass mac download.
Ubuntu Grub2 Config
Most likely for pre-2005 installs.
For the 2005-2010 period, your guess is as good as mine, but if you use the command for the wrong version, you only get a harmless syntax error on the first command.
At startup, grub will probe for your devices and assign numbers to them. All devices that are partitioned (hard disks and flash drives) will also have numbers assigned. The format is
(<deviceName>,<partitionIndex>)
. In grub2
, partition indexes changed, so the two examples above have the same effect despite looking to use different roots.Your first device (
hd0
) is whichever device grub just loaded from. After that, you can usually assume that all the internal devices will come before your external devices. Embroidery software for mac download. They will most likely be in the form of hd
and a number.After the comma is the partition index. Hard disks and thumb drives will almost always be partitioned, so you must choose the right (and most likely only) partition. CD-ROMs are usually not partitioned.
More documentation: http://www.gnu.org/software/grub/manual/html_node/Device-syntax.html
When choosing your root partition, you can use the Tab key to probe for device names and partition indexes. Just open parenthesis and start pressing Tab to see the list.

Gw1 download all maps mac. To elaborate on new123456's comment:
The USB device should be detected as a mass storage device and treated just like a hard drive. So, in grub, type
root (hd
(don't press Enter yet) and then hit tab once or twice to see what hard drives Grub can see. The USB device, if it's recognized, will probably be hd1. Don't specify a partition number; just add a closing parenthesis. So the line will be root (hd1)
. Then after that, type the following:If that doesn't work, change
root (hd1)
to root (hd1,0)
and try it again.If for some reason Grub can't see the USB drive, try plugging in a USB CDROM and booting off that.

The
chainloader +1
thing might not work if the BIOS isn't good at booting from a USB key (which was why I was wanting to use Grub anyways). In this case, there's some deep magic at https://help.ubuntu.com/community/Grub2/ISOBoot that works, at least for Ubuntu. The crucial bit is mucking with the grub command that identifies the
vmlinuz
file, passing the iso-scan/filename
argument. Somehow, that helps it figure out that the entire boot filesystem is stuck in an ISO file. I don't know how the heck it works, but it does. These are (approximately) the Grub 2 commands I used:The
/path/to/iso/file
should be the path to the ISO file on the USB key. The (fd0,msdos1)
identifies the USB key. Tab-completion is super-helpful on the loopback
line, and not useful for the arguments to vmlinuz

Office 2011 keygen. This isn't going to be terribly helpful in your friend's case (unless there's a way I'm unaware of to get plop on the device in the first place -- maybe a usb cd-rom, or usb floppy drive?), but this is a terrific little application, which has helped me rig a number of old machines to boot off of usbs when their bios wouldn't allow it.

You can't boot from usb in grub if the bios doesn't allow for it itself. I once had to setup a sort of recovery partition on a hard disk containing the win7 setup disk contents, install grub, and then used that to boot the win7 setup partition to install it to the rest of the hard drive.

I have Windows 8.1 installed on an SSD in my PC. It is my main OS and I use it the most. I currently need Linux for development purposes and I installed Linux Mint on the same SSD where Windows is installed. I want to have a USB flash drive, which, when plugged in, will show the GRUB bootloader and let me boot into Linux. Otherwise the PC should boot straight into Windows. When I was installing Linux Mint, I selected the USB flash drive as a 'device for bootloader installation' but it seems that nothing was installed on the flash drive but I now have an 'ubuntu' option in my UEFI BIOS boot devices list, which just launches Linux from its main partition and does this in Legacy BIOS mode, even though I installed Mint in UEFI mode. Also, I think that nVidia graphics drivers don't work because of the Legacy mode.
https://everglow919.weebly.com/blog/how-to-hack-on-terminal-mac. Can anyone provide me a complete, step-by-step noob tutorial on how to make a UEFI and Secure Boot compatible flash drive and install GRUB2 EFI on it, so it will let me boot into Linux Mint installation straight from the flash drive?

EDIT: To explain a bit more what this will do. This will install a bootloader on your USB drive and it will allow you to enter a bootloader when plugging the USB drive in the computer. Booting the OS' on the computer.
!This is not grub but it does exactly the same.!
