Can't boot from a USB

Hi guys,
Fist my laptop is a Toshiba satellite P870 and I've been trying for weeks but I can't boot from a USB, I mean, I've been used programs like: power ISO, ultra ISO, Linux live USB creator and nothing! But if I try to doing it in other notebook or PC with the same USB it boots without any problem. So I would like to know if theres a trick or something that I'm missing.
By the way it happens the same when I try to use a CD or DVD, bootable, of course.
Hope you can help me out!

Have you set your boot Priority so that the USB is highest?

Tecra M2: Can I Boot from External USB/Firewire-HDD ???

Hi All,
how can I boot from an external USB Drive ?
The Bios 1.20, 03/15/2004 doesn't seem to support this on my Tecra M2.
I have an Maxtor 300Gig external HDD which can be connected via Firewire or USB. Usually I am using an Firewire PCMCIA-Card to connect this HDD, which has 3 partitions on it.
Would it also be possible, to Boot via PCMCIA-Firewire ?
Many thanks in advance.

Hi
As far as I know its not possible to boot from a USB HDD. I know that in some cases its possible to boot from compatible USB FDD and CD/DVD drives but note from HDD.
This theme was disused a lot of time here in the forum.

Satellite L20-100 can be booted from external USB hard drive?

I recently bought Toshiba Satellite L20-100 and I wonder if:
1. is there any possibility to boot this machine from external usb hard drive?
2. it is possible to attach another internal hard drive?
Supposing that the both answers above are 'no', how can I solve the following problem: I need hdd space, I need to boot 3 separate Wxp Operating Systems onto the same machine (Toshiba Satellite L20-100).

Booting from external USB HD - "No" would be the official, mcrsoft sponsored, answer. However, it is possible. Not easy but it can be done. I've seen it done with my own eyes and there are guides how to do this. Just look for it with search engine. But if you have enough disk space you better do what was suggested here - create 3 partitions and use boot manager.

Satellite U400-15E - Can't boot from new USB HDD

Hello.
Recently a bought an external WD My Book with 3TeraByte to use with my Satellite U400-15E. I can use it inside Windows 7 Ultimate with no problem. But if I try to boot from it (by pressing F12 key), the BIOS doesn't even see the drive.
Is this because Toshiba doesn't use Unified Extensible Firmware Interface (UEFI)? UEFI BIOS can overcome the 2.19TB limitation in todays computers easily, like the following Western Digital document explains:
[http://www.wdc.com/wdproducts/library/Flyer/ENG/2579-771501.pdf]
This would allow me to use my new external drive to store a Ghost image of my Toshiba's internal HDD for instance. I mean 3TB and even greater capacities are a reality today. When will Toshiba update their BIOSes to support UEFI?
Equipment used:
Toshiba Satellite U400-15E (BIOS v5.00 26-10-2010)
Western Digital My Book Essential 3TeraByte - Firmware v1.014 (USB 3.0 interface)
MS Windows 7 Ultimate - 32bit version
Thank you

Hello
Well... with this same computer, I already tried booting (successfully) from the following pendrive capacities:
8GB
16GB
32GB
All without problem.
And besides, before having the 3TeraByte WD, I had a 1TeraByte Iomega USB HDD from which I could store Ghost images, because the BIOS would show the 1TB Iomega drive after pressing F12 and Symantec Ghost could also detect the drive without problems.
But with this new 3TeraByte WD... the BIOS doesn't even show the drive after pressing F12.
So when you say +{color:#0000ff}So USB HDDs are not supported{color}+ are you refering booting from USB HDD?
Hum... I'm not sure about that.
I never tried booting an OS from the Iomega.
But that was never my purpose either.
My purpose is for the BIOS (and hopefully Symantec Ghost) to detect the WD USB drive, like it happened before with the 1TeraByte Iomega.
I was using a 1TeraByte Iomega "Select Series" drive.
With the Iomega I could create Ghost images of my Toshiba without a problem.
+{color:#0000ff}But you’re absolutely right: 3TB and greater capacities are reality today but Satellite U400 is older notebook model and not newest one.{color}+
A Laptop computer that has Two 64bit CPU cores and 8GB RAM capacity is not that old!
I think it could be a BIOS limitation, since it's not using UEFI.
Any more ideas?
Thank you.

X121e can't boot from external usb cd rom

Hi all,
This has kept me busy all day. Read many threads and tried lots of things...but to no avail. I hooked up an external cd-rom drive tot my X121e and changed the boot order to start with the USB drive. Somehow it just doesn't want to boot from cd-rom....Played with the UEFI settings, tried different cd-roms and dvd-roms, but nothing works. It sounds like the X121e is rebooting itself when it reaches the cd-rom drive (the screen stays black so I can't tell for sure).
When I boot from a different laptop the drive works straight away.....
Did anyone succeed in booting the x121e from an external cd-rom drive?
Thanks in advance!!!
usb4life

Did you try an DVD drive instead? Do you have the most recent BIOS firmware?
I was able to boot my X121e from an external DVD writer but I havent't tried a CD-ROM.
What does happen if you try to boot? Can you be more verbose?
Are you able to bring up the boot device selection menu? Is the drive being listed?

Can't boot from a USB flash drive

I believe this ability was lost after updating to BIOS 80.52 following HP's "strong recommendation".No warning was given that this update would remove this ability and see that "Due to security changes, after this BIOS update is installed, previous versions cannot be reinstalled."
I have tried disabling Secure Boot and enabling Legacy Boot, and tried re-applying BIOS defaults.
Is there a particular combination of BIOS settings that I haven't been able to find?As the warranty on my computer expired in July 2014, the HP Customer Support Contact page won't even accept my request for assistance - despite the "strongly recommended" BIOS update being made available *after* this date. I require the ability to boot from USB flash drives ... how can this now be achieved?
Is there an HP BIOS for a more recent HP product with the JasmineR motherboard (or an AMI or other BIOS) available and how could I install it?
Boot a BIOS flashing program from CD or DVD and somehow bypass the HP BIOS's block on updates? Thanks in advance for any advice

Hi, thanks for the quick reply. I don't have another PC handy but will try to find one. The USB flash drive definitely does NOT appear in the boot menu - even as an HDD or CD/DVD as I have seen mentioned elsewhere as a possibility - and all USB devices are enabled in the BIOS settings and USB HDD and USB Floppy/CD are above rEFInd and all other entries in the boot order. I should also have mentioned that I've tried a (Lexar) USB flash drive prepared approximately a year ago with GParted Live which *has* previously booted the machine, and also different models of flash drives (Toshiba, Transcend) and different methods of preparing them such as burning bootable ISO images with Win32DiskImager, Universal USB Installer and Rufus, and manually creating and formatting a bootable FAT32 partition with diskpart (as per https://technet.microsoft.com/en-us/library/jj200124.aspx) and copying in System Rescue CD/GParted/Clonezilla files, ensuring there is an /EFI/BOOT/BOOTX64.efi file. In diskpart, the "attributes disk" command shows that the USB drives are not marked as bootable and "help attributes disk" says READONLY is currently the only disk flag that may be changed. (Don't know if this means anything as the GParted disk isn't "bootable" but did boot) Did the BIOS update disable enumerating USB devices until later in the Windows 8.1 boot process?

Can't boot from external USB DVD reader

Hi! I have a Lenovo IdeaPad S400 and a Samsung external DVD reader. Once, I've installed Windows 7 from that reader. Now I've got Ubuntu 12.10 and want to instal iATKOS ML2 and it just doesn't boot from that reader. It's not just that DVD. I've tried with the same Windows 7 and other Ubuntu disc but it doesn't show up neither.
I'm pretty sure that's something to do with the BIOS, but I can't figure out what!
Hope you can help me. Thanks!
Solved!
Go to Solution.

hi Tiiiincho,
Welcome to the Lenovo Forums.
Can you try to:
1. Press the One Key Recovery button on the left side of the PC and access the BIOS setup utility
2. On the BIOS, navigate to the Boot Tab and set UEFI Mode to Disabled.
3. Insert your iATKOS ML2 or any bootable installation disc and press F10 to save and exit BIOS.
4. During boot-up, hold the Fn key and continuously tap F12 and select the ODD drive on the boot manager.
Your iATKOS ML2 or any bootable installation disc should now start.
Hope this helps.

How can I boot from USB 3.0 disc on a Mac Pro 2013

I am just setting up a 2013 Mac Pro with a 4TB USB 3.0 external drive. I have cloned my boot disc over to it but have problems being able to boot from the USB drive.
It shows up in the startup disc in system preferences, but when selected as the boot disc and restarted it just boots from the internal SSD. Also have checked booting and holding the ALT key to see what happens but I am just shown the SSD and Recovery disc as options to boot from.
So it appears I can not boot from a USB disc on my new Mac Pro, is there a solution to this problem?

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

Booting from external USB drive

I was wondering if there is any way to boot from a USB drive that I have? I partitioned the drive, erased it, and its basically ready to go. But I can't install Mac OS X on it because it says that I cannot reboot from the drive.
I know that iBook G4s generally can't boot from a USB devise but is there any way to get around this?

If you're computer is having kernel panics there's a conflict; either software or hardware. 2GB of free space isn't enough but I haven't seen anything that suggests KPs are caused by too little free space. Your computer should start fine with 2GB free. It may have problems after a period of use but it would startup and run.
Try starting in Safe Mode. If successful move some of your files to the external drive and then restart normally. If it KPs again, restart in safe mode and disable all startup items in System Preferences>Accounts>youraccount and restart. If it KPs again go through the linked troubleshooting steps by Dr. Smoke step by step. That's the only way to resole your problem.

How Can I boot from USB - Portege A200

Hi,
I've got an Portege A200 which is only a couple of years old but the hard drive no longer works. Initially I thought this was due to corrupting the boot record on the drive but after attempting to replace the hard drive (with two different drives) it is showing an IDE #0 error upon boot. I have therefore come to the conclusion the IDE controller chip has died.
In order to get the latop working I burned a cd with the ubunto ISO. This boots ok but due to only have 512Mb RAM the system is somewhat limited and anything installed is lost everytime I reboot.
I have now bought a 2Gb flash drive and installed ubuntu onto this. My next problem is that there appears to be no boot from USB HDD or USB Memory Stick option in the bios.
The possible options that I can think of are:
1) Upgade the bios so it supports boot from memory stick (although no HDD so not sure how I could reflash the BIOS or if there is even a BIOS upgrade that would support this functionality)
2) Create a cd which starts the boot process then tells the system to continue booting from the usb drive (Is this possible and does anyone know where I might be able to obtain such software)
3) Boot from CD but use the USB to retain any information saved / any installs etc (I guess similar to option 2 except the cd would manage the whole OS and the USB would just hold 'additional' information)
If there are any other options that anyone can think of I am happy to give them a go. Seems a shame to have to chuck a laptop that isn't particularly old because the IDE controller chip has failed on the mobo.
I apppriciate any help anyone can offer.
Many thanks,
Mark

Hi
First of all I have to say that its not possible to boot from the external USB device like the USB stick, USB CD/DVD drive or USB HDD.
Its possible only to boot from the external USB FDD (diskette) drive
However, not the booting possibilities are clear but I think you have misunderstood the IDE#0 error message. In m opinion the IDE controller is not faulty but only the new HDD is not compatible and not recognized by BIOS.
There are different reasons for this issue
Mostly this error message appears if the HDD master/slave/c-sel settings are not correct.
Usually such settings dont need to be changed or switched on 2.5 HDDs but some HDDs support an jumper which must be set in the right position. But I dont if your HDD supports this
Furthermore the not compatible HDD size could be the reason for such error messages!
So finally I would recommend contacting the ASP in your country to get a new, compatible HDD and to check if the same error persists.
Good luck

Imac 21" mid 2011 can not boot from USB device?

Hi,
hope someone can help me.
Bought the new imac 21" and replaced the superdrive with a ssd drive.
Works great but it seems that the imac is not able to boot from any usb device.
I put my osx install disk in my external dvd drive and powered my mac.
While booting up (pressing cmd) the mac does not recognize my external dvd drive. This works great with my MBP late 2008. But the imac can not boot from the dvd drive. Also pressing "c" while booting does not work. Doing that a grey screen appears and after some time mac boots from hdd.
So i installed mac os via target mode over firewire withbmy old imac. This works.
But now i want to install windows on a bootcamp partition.
I can't boot from the windows 7 professional dvd, too. So i tried to create a bootable win 7 thumbdrive. Mac can't boot from this too. Reading many threads in some forum i tried with rEEfit. Reefit shows the usb thumbdrive whike booting, but using this will end in a black screen error from bios: "no bootable device....". Tried a knoppix on the usb thukbdrive, too.... No bootable device....
It seems that there is no way to boot from ANY external usb device like dvd drives or thumbdrives......
What more can i do? I tried for 2 evenings now, but nothing worked out for me......
Currently i don't see any any to install win 7 without an internal superdrive, but can this be??
Thanks for any comments.
Kwicks

Internal is definitely the easiest but you can boot from external HD or external optical drive, the mac is just very picky on what works and what doesn't.
For an external drive or usb stick it has to be GUID partition table and have 10.4.5 or better installed on it, for more info check this link out ( http://support.apple.com/kb/ht1948 )
Hope this helps,

I can't boot from OS install USB drive Mac Mini Model 1176

How I can't boot from OS install USB drive, Mac Mini Model 1176

Thank you Eustace Mendis for your answer.
I rebooted the Mac Mini holding the Option key down but it doesn't work. I used an USB drive with O.s 10.7 from Apple that I have used previuosly with other computers and I also tried with a CD install O.S 10.6
It seems that the Mac Mini can't recognize the keyboard inputs and I tried with 3 different keyboards but still didn't work.
I also reset the SMC and PRAM but I had no luck. Any clues?

Can't Boot from bootable CD/DVD or USB.

I'm trying to install a new OS from a bootable DVD that I created. However, my T530 will not boot up from the DVD. I checked the boot order in the BIOS settings, and even explicitly tried to force to boot from my DVDROM usint the F12 boot menu. I've been able to boot from this DVD on my other computer.
Any way to diagnose whether my DVDROM is faulty, or is there perhaps some BIOS setting to fix this? I am able to read the disc from Windows, just can't boot from it. The laptop is brand new, just opened it up today, so I don't know why something as simple as this wouldn't just work.
Solved!

Next, I copied the ISO image to a USB stick and tried to boot from that instead. But it hung. I was able to boot from the same USB stick on another laptop.
All the signs seems to suggest the laptop is simply defective, which is extremely disappointing considering it is brand new and I waited for about a month to receive it. Is there anything else I can/should try (some diagnostic utility, perhaps?), or do I just send it in for a replacement?
Is you used the tool at http://www.microsoftstore.com/store/msstore/html/pbPage.Help_Win7_usbdvd_dwnTool to take the .ISO file and create the USB stick, I'd say you are right and have an issue with the system.
Did the system ship with Windows 8 and is safe boot turned on?
Yes, it is Windows 8 with Secure Boot on by default. I tried it both with it enabled and disabled, and it didn't work either way.

[SOLVED] can't boot from ssd after "reset" from recovery usb flash drive

I have a Twist s230u with the original Hitachi 500GB hdd, running Windows 8.1. I want to replace the Hitachi 500GB hdd in my Twist s230u with a PNY 240GB SSD that i've purchased.
While running Windows from the Hitachi HDD drive I followed the "create a recovery drive" procedure to create a recovery usb. Then I removed the Hitachi HDD from the s230u and installed the PNY 240 SSD in its place. I booted the s230u from the recovery flash drive that I made. I selected the "Reset Your PC" option and then the option to wipe all partition/files. After the Reset completes, I try booting from the SSD but am unable to do so. I just go back to the F12 boot menu.
I put the SSD in a drive dock attached to another computer. Disk Management shows the partitions as follows -
I've looked at the partitions on the SSD after the Reset - Disk Management console shows a 1000 MB Recovery partition, a 260MB EFI System partition, and a 221GB primary partition with volume label Windows8_OS. It is not marked as Boot, Page File, or Crash Dump.
Diskpart shows an an additional 128MB Reserved partition between the EFI partition and the primary partition.
I do notice that the 10.6 Lenovo Recovery partition is not present - but I did make sure that I included that partition on the recovery key - though the files on the recovery key only use 8.03 GB for some reason. Made the key on two different flash media.
Diskpart also shows the following for the SSD:
DISKPART> attributes disk
Current Read-only State : No
Read-only : No
Boot Disk : No
Pagefile Disk : No
Hibernation File Disk : No
Crashdump Disk : No
Clustered Disk : No
(It also looks like this when I run DISKPART from the recovery media with the SSD inside the internal drive bay of the s230u.)
When I did the Reset on the SSD in the s230u, and when I tried to boot from it - I had the Secure Boot disabled, the "Legacy Boot first" option set, etc.
Can anyone point me in the right direction to be able to boot Windows 8.1 from this SSD in the s230u? I've been working on this for a couple of days.
(I also tried cloning the HDD to the SDD using Minitool Partition Wizard, Macrium Reflect, Clonezilla, Acronis, etc - the SSD wouldn't boot after those clone operations either, and I thought maybe I'd have better luck with a reinstall from the USB recovery media.
(I also tried installing from a Windows 8 iso I burned to a DVD. I got a product id mismatch message when I tried to install from that, and I was not allowed to proceed.)

well, I seem to have solved my own problem. Maybe someone will learn from my mistakes.
I went into System Setup, went to the Startup tab, and changed the boot setting from "Both" to "UEFI Only". After doing this I booted from my USB recovery drive, and Reset the PC. After the Reset, I booted the s230u from the ssd, and I booted into a fresh Windows 8 installation.
It seems that the Reset operation could not work properly while the boot setting was "Both" (UEFI and Legacy) and "Legacy First."
I got a clue when I looked at the contents of the EFI System Partition and there was nothing there except a Temp folder. The EFI System Partition had not been properly written by the Reset operation. I got some helpful hints on how to see the contents of the EFI System Partition here - http://www.fixedbyvonnie.com/2013/12/how-to-repair-the-efi-bootloader-in-windows-8/#.U-Qz2_ldW7q
I've also buggered up my original HDD now, so that it won't boot to Windows now. Now to fix that!

Can Satellite L40-139 boot from a USB device?

Hello,
I have a new L40-139. Looking through the BIOS I cannot find an option to boot from a USB device such as a USB HDD or USB flash drive. Could someone confirm if teh L40-139 can boot from USB, and is so how to configure the BIOS for this.
If it cannot does anybody know if there are plans for a BIOS update that would allow this?
I have to admit that while I like the L40, I am disappointed at how limited the BIOS is.
Thanks,
R

Hello
I am not 100% sure but, as far as I know, you can not use USB HDD as first bootable device. USB FDD yes, but with external HDD it will not work.
