BIOS modify to boot into usb?

Hello world!
I have a bootable usb drive, but I need to change the BIOS options to boot into my usb. First, how do I access the BIOS on my mac? Second, how do I change the settings so I can boot into my usb?
Thank you!

If the USB drive is bootable and has something on it to boot from, them all you need to do is select it in the Startup Disk Preference
or restart holding the Option key and select it from the Startup Manager.
See > Startup Manager: How to select a startup volume
If not, then see > Starting from an external USB storage device (Intel-based Macs)

Tecra 8000: Does Bios Update enable booting from USB?

Hello
I have Toshiba Tecra 8000 (PentiumII 266MHZ)
Will this bios bios-t8000-930-trad.zip (08/26/02) enable boot from USB ?

Hi
Im not sure about that. Your BIOS version is 020 but on the Toshiba website I have found a BIOS version 9.30. Well, it seems that this version is newer but Im not sure if it allows you to use the 40GB HDD.
Some Tecra 8000 models were delivered with a 14 GB HDD. In my opinion it should be possible to use a 20 or maybe a 30 GB HDD but its difficult to say if the bigger HDD size will work.
You can ask the professional HDD dealer or a ASP for further informations.

Cannot boot into USB

I have a Toshiba NB525 PLL52C-029003 and when I enter the boot menu (by pressing f12) I can only select the HDD or LAN. However, because there is no CD drive, I would like to install Ubuntu via USB. Is there an issue with the BIOS or would it be related to my USB ports?
Cheers

This is the site for U.S. machines and yours is from Canada. All support, downloads, etc. for your machine are located HERE. Normally, USB won't show in the BIOS boot options unless there is a bootable USB device plugged in. I would assume if I inserted a bootable device in any USB port that it would be bootable if I made the selection in the BIOS.

BIOS won't boot freshly installed Arch [solved]

Hello
Last night I did a complete wiping of my hard drive on my old HP620 laptop in order to start my ideal Arch setup from the scratch.
I decided to give GPT a try, since I've been sick of the brain damaged MBR all those years. I did the install as usual, using cgdisk
to partition the drive within the freshly created GUID partition table. I made up 5 partitions, with the leading 1MiB BIOS boot partition,
which I created inside the first 40-2047 sector boundaries and set it to type ef02.
Everything has been alligned properly and passed without any errors. I partitioned the drive as follows:
quetzalcoatl% sudo gdisk -l /dev/sda
GPT fdisk (gdisk) version 0.8.10
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Disk /dev/sda: 625142448 sectors, 298.1 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 1DC6DA85-2730-4101-ADA1-69EA884CC1B7
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 625142414
Partitions will be aligned on 8-sector boundaries
Total free space is 362996373 sectors (173.1 GiB)
Number Start (sector) End (sector) Size Code Name
1 40 2047 1004.0 KiB EF02
2 2048 52430847 25.0 GiB 8300
3 52430848 85985279 16.0 GiB 8300
4 85985280 94373887 4.0 GiB 8200
5 94373888 262146047 80.0 GiB 8302
sda1 is BIOT boot partition, sda2 is /, sda3 is reiserfs /var, sda4 for swap and sda5 is /home.
I formated every partition prior to mounting and installing the base system, except for sda1 which
I left intact (no formatting, just the cgdisk part of creating and chosing type).
At the end, I did the grub installation and configuration:
pacman -S grub-bios
grub-install --target=i386-pc --recheck /dev/sda
pacman -S os-prober
grub-mkconfig -o /boot/grub/grub.cfg
after which I unmounted and rebooted, but the BIOS refused to boot into the system. It came up with the "Non
system disk or disk error". The only way of booting into the system remains to use the Arch installation CD,
and chose "Boot from hard drive" option.
I tried adding the boot flag to the BIOS boot partition using "parted /dev/sda set1 bios_grub on", and even faking
and adding bootable flag to BIOS boot partition using the MBR's fdisk since gdisk hasn't got the option to.
Nothing helped.
Pacman says GRUB version is grub 1:2.02.beta2-4. Should I try going with syslinux or my BIOS (which I hadn't been updating at all)
is perhaps too old or buggy to cope with the GPT? I don't want to convert to MBR, if technically would be possible to boot using GPT.
What should I do?
Thanks in advance,
Luth

Hi Luther,
As the thread hasn't been marked as solved I hope this will help:
1. The standard partition table type used by BIOS systems is MBR/MSDOS. Any PC released prior to Windows 8 should be a BIOS system. GPT is a newer partition table type used as standard with UEFI systems (i.e. post Windows 8). To make life simple, it is recommended to stick to the standard partition type appropriate for your system.
2. The performance gain you would get using Reiserfs - I suspect - would be negligable. Ext2/3/4 would be a better choice, particularly as they are easy to use and are very popular (i.e. better chance of getting advice and support if you need it).

10-K010CA laptop cannot boot from USB

I try everything ( update BIOS, disable securiy boot, setup usb boot first ). But the laptop will not boot any other USB disk except the Recovery USB Disk create by the laptop.
I had a few USB Disk ( windows 7, linux ) which boot normally on HP Desktop PC which set to boot UEFI but will not boot from this laptop.
Will this laptop able to boot from USB Disk at all?

P67a-GD80 won't boot from USB HDD

Trying to boot from a bootable thumb drive.
I've got the bios checked to boot from USB HDD first.
Still boots from HDD.
When I disable second & third boot devices (hdd & cd-rom), I get the message "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key".
Ideas?

Mine is like "USB Key: *My thumb drive name"
Do you have a GD80?

Can't boot into Windows 8 Single Language 64 bit or access the BIOS screen with the F1 key

I have in my possession right now a Lenovo E49, Model name: 3464
I am unable to access the BIOS settings at POST by pressing the F1 key. Neither does it respond to the Enter key when it displays the message "To interrupt normal startup, Press Enter". I am also unable to boot into the installed OS Windows 8 Single Language 64 bit.
For your informtion, these are the events that led to this issue.
I accessed the BIOS settings at startup using the CHANGE PC SETTINGS option in the CHARMS menu in Windows 8 Single Languge 64 bit followed by GENERAL and ADVANCED STARTUP. Then I chose Restart Now. Windows restarted to produce the startup screen where I chose Troubleshoot, followed by Advanced Options and UEFI Firmware Settings, followed by Restart. This took me to the BIOS settings screen. Once there I changed the boot settings in BIOS so that SECURE BOOT was turnned OFF. It was in ON state prior to that. I also changed the BOOT MODE to LEGACY ONLY. I also changed the BOOT ORDER to boot from DVD drive first followed by the Hard Disk and USB Hard Disk. I saved the changes by pressing F10.
Now the computer is able to boot from the DVD Drive. I tested this by inserting a Windows 7 Repair DVD and also a Linux Live DVD. Mind you, I didn't mke any changes to the Hard Drive. I'm also able to boot from a USB Hard Disk. This too was tested by inserting a bootable USB HD that had both Windows 7 and Windows 8 OS installers. I used only the command prompt feature in the Repair option on the Windows 8 installer to ensure that I could access the partitions on the HD. I did not in any way install Windows 7 or 8 on the HD.
If there is no bootable DVD or USB HD inserted, the laptop is involved in a loop that restarts followed by a message that says the following:
"Intel Undi, PXE-2.1 (build 083)
Copyright (C) 1997-2000 Intel Corporation
This product is covered by one or more of the following patents:
US5, 307, 459, US5, 434, 872, US5, 732, 094, US6, 570, 884, US6, 115, 776 and US6, 327, 625
Realtek PCIe GBE Family Controller Series v2.41 (06/08/11)
PXE-E61: Media test failure, check cable
PXE-M0F: Exiting PXE ROM."
I am positive that the current state of the BIOS is such that it does not accept any input keys like F1 and F12 at POST so that the BIOS can only be accessed through Change PC Settings in Windows 8 as I had done prior to the occurence of the issue. Since I cannot boot up Windows 8 I cannot use this method to access the BIOS. And since it is not possible at this stage to access the BIOS settings through the F1 key, I believe Lenovo must have surely provided another alternative to enter the BIOS. Can you kindly tell me what other way is there to do this. In earlier days, one could reset the BIOS by shorting the BIOS through pins on the motherboard. Is that possible now? Or is there some Lenovo BIOS utilily that enables me to change the BIOS setting to boot with Legacy and UEFI? Or do I have to install Windows 8.1 64 bit in Legacy mode?

I'll see if another member of the team can jump in here and offer more help...
What I might imagine is that you can only access BIOS from a cold boot. Windows 8/8.1 have hybrid shutdown and don't completely shut down the machine normally, so even when it powers off, it isn't fully off and the next boot is not really a cold boot.
Please see this KB. I realize this assumes you can get into windows.
As you suggest, it also seems as though you have set legacy vs UEFI and that may be why your drive is not currently booting. Can you remove the battery on your system? If not, is there a reset hole on the bottom? Removing battery and AC and pressing and holding the power button several times, then re-attach AC and Battery and try to restart and press F1 to get into BIOS. (Not familiar with models that use enter for BIOS).

K7T Turbo2 - how do I tell BIOS to boot from USB?

I have an old K7T Turbo2 system, and I'm trying to install Windows 7 on it. I guess that's my first question - am I going to run into any nasty problems running W7 on this board, other than RAM limitations? I have a version of "Tiny7" (which installs from CD-ROM) installed already and it seems fine, but I'd rather run a fuller non-pirated OS, and that means installing from a DVD/iso. I don't have a DVD drive installed and it would be a bit of a pain to acquire one, so I'm hoping to boot from USB to winstall W7.
I have a PCI USB2.0 card installed in the system, which seems to work fine. I've set the BIOS to boot from USB-FDD (but I've also tried USB-CDROM and USB-ZIP). I have BIOS 3.6. I've tried booting from the PCI USB2.0 hub (will that ever work or does the BIOS not recognize it?) and from the regular USB1 port on the mobo (but my USB flash drive is USB2).
Is there something else I need to do in the BIOS to get this to work? Will it never work no matter what I do?
I read somewhere about a BIOS setting to "enable legacy USB support" but can't see anything like that in my BIOS settings.
Any suggestions? (thanks in advance)

If there is no option to boot from USB-HDD then it may never work.
Long shot I know, but what if you connect your USB drive, then power on your system, and press F11 when the logo/POST screen appears, does the drive show in the Boot Menu that appears?

Really? DVD drives are very common, and cheap as chips! You can pick up a brand new DVD writer, for the price of a (good) DVD movie.

Not able to boot into Ubuntu live CD or USB - Satellite A300-13S

Hi there,
I hope someone can help me on this. I've just got a new A300-13S pre-installed with Windows Vista Home Premium. I've managed to create a recovery DVD (after having the same hassle about having to use a specific brand of DVDs, as mentioned in other posts), and have tested the DVDs, which work fine.
My problem is this: I would like to dual-boot with Ubuntu 8.10 and so have created a live CD to test that everything works before I carry out a full installation. I rebooted, but the laptop doesn't seem to see the live CD and boots straight into Windows. I have tried both the boot manager on F12 and changing the bios boot order via F2. Strangely enough, when the bios boot order is changed, Windows then can't see the DVD drive (via My Computer - I haven't checked other routes to the drive).
I know that the DVD drive works during boot-up because I can boot into the Windows recovery DVDs.
I thought that it could be a disk compatibility problem, but I can access the contents of the ubuntu CD (when the HDD is first in the bios boot order). I've also tried copying the files to a USB stick. The laptop can see the drive during boot-up, but won't consider the iso as a valid system. I've done the relevant md5sum checks and they are all fine. The live CDs also work in another computer.
Does anyone have any suggestions? Am I missing something?
Thanks in advance - this is starting to drive me a bit nuts.

Thanks for the suggestion. I've tried changing the SATA setting but that doesn't seem to have solved the problem. Any other ideas?
Cheers in advance

U410 Bios won't save settings to boot from USB

Hi-
I'm having some major issues with my system, so I'm trying to boot from a USB into my Windows Recovery disc.
The only way I'm able to access the BIOS is by going into the machine and disconnecting the CMOS, which forces the BIOS to come up. I change the boot order to have USB Boot first. However, when I reboot, it goes into the boot manager (GRUB).
I've tried it several times, changing the boot order, then saving it, then rebooting - always ends the same way.
I've seen all the other u410 BIOS-related issues on the forums, but this seems to be fun, slightly different twist to those issues.
Any help would be appreciated. I can't really do anything, and I'm stuck in limbo if I can't get it to boot from a USB.
Thanks.

Since you stated GRUB, I'm just curious and I would like to know if you have installed another OS aside from the pre-installed one.
Thanks in advance.

Will MSI Z87 MPOWER Motherboard boot into Bios with Devils Canyon?

Hey guys !
I decided to take the plunge and update to a Devils Canyon i5 4690k and purchased a MSI Z87 MPOWER motherboard which was on special. I know I need to update the bios for this cpu.
I forgot to check something crucial !
Will i be able to boot into UEFI Bios and update the Bios with this CPU ???? I have only used ASUS Mobo's and they have the bios flashback feature. I'm worried i'll have this great mobo and cpu and not be able to update !!! I don't have a standard haswell cpu to use just to update the bios to support Devils Canyon.
Could someone confirm if it will boot allowing me to update via the MSI Bios flash method.
I still have time to cancel the order if need be.
Thanks !!!!!!!!!!!!!!!!!

Not quite automatically. It will recognise the CPU but may not properly work or boot. You can try booting into Windows/other OS, but you might need to update BIOS.
Once you have the updated BIOS prepared on the USB stick, you just boot from the USB stick and it will give you some instructions etc to follow, and that's all about updating.
As last resort if it won't let you do it, you can take motherboard to some PC repair center where they have SPI programming tool and they'll update BIOS even without the CPU inside

Stream 7 refuses to boot into BIOS

Tablet won't boot into windows or to the BIOS using the volume down and power keys.

You might try plugging the charging cable into another computer's USB port to see if you can get the pictogram to display (to rule out that the AC adapter is not bad). If you still cannot get the pictogram, the tablet has probably failed and is in need of a warranty replacement.

NF750-G55 - Does not detect usb mouse (have to plugin after boot into Windows)

Topic says it all...
Mouse is Microsoft Habu, has been working in my old system just fine (ASUS M2N32-SLI DELUXE). The only usb items plugged in are the mouse and my Logitech G11 Keyboard.
I just upgraded my old rig to what you see in my signature, my mouse will not get detected unless I replug it in after windows has started.
During boot after initializing usb controller it says Found: 1 Keyboard and 1 Hub
I have tried the following but with no successful results:
PS2 Keyboard with mouse (mouse behaves the save)
Mouse w/usb->ps2 adapter (mouse lights up but doesn't do anything in windows)
Mouse plugged into every different port on the MOBO, D-Bracket, front panel usb or even into keyboard
Different mouse (boot says Found: 1 Keyboard, 1 Mouse, 1 Hub) and this mouse works all the time
USB Legacy On/Off inside bios
I also have a USB powered hard drive (http://www.simpletech.com/products/storage/simpledrive-mini/red-wine-250gb.php) that when plugged into the motherboard was making a beeping sound but I can't find any information on what that means (if anything)
Any ideas?

I had a similar problem with a couple of different boards, but with a Razer Copperhead mouse. I ended up just buying a new mouse (PS/2 type).

Satellite A100 PSAA8E: Cannot boot from USB after Bios update

Hi
I downloaded the latest bios (v6) for my satellite a100 (psaa8e) and after updating the old bios, I noticed I can't boot from USB. Is there a way to restore the old bios or will this problem be solved?
Cheers
mo

I used to press F12 after restart and choose from USB. After downloading the bios, the system refuses to boot from the USB (external CD drive). However, if I place the same CD into the unit's CD drive, and choose boot from CD after pressing F12, the unit boots fine. This only happened after the bios update.
Thanx
