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
Mo

Satellite U925t cannot boot from USB

Hi
I cannot boot from USB flash drive on Satellite U925t. I use bootable USB flash drive inserted (Hiren Boot 15.2, sure booted on another laptop), restart the system. When the splash screen is displayed, press F12 to access the boot menu, selecting USB - but laptop no boot from USB.

Thank you very much

From within Windows, try holding SHIFT when you select Shut down. Is there any change then?
Also, try entering the UEFI settings, disabling Secure Boot, and changing UEFI to CSM.

Satellite C50-A634 wont boot from USB or DVD

My new toshiba Satellite C50-A634 wont boot from usb, or dvd ,
i have downloaded win 8.1 and burn image to dvd but i still get an error message "no bootable device......please restart system" .
Can some one plz help?

Hi
Does Satellite C50-A634 supports internal CD/DVD drive or did you try to boot from external optical disk drive?
You have to know that _Satellite C50 & Satellite C50D models *without* a built-in ODD_ are not able to boot from an external ODD due to a technical limitation.
Details here:
[Limitation of external boot media for Satellite, Satellite Pro C50 & C50D devices|http://aps2.toshiba-tro.de/kb0/TSB3B03JA0000R01.htm]
Only USB flash drives are supported as external boot devices!
It is necessary you can use a USB flash drive as recovery media on notebooks without a built-in ODD.

Can i try archlinux on usb if my pc cannot boot from usb?

it seems my old pc cannot boot from usb, only boot from hd or cd.
can i use usb? or i have to burn a cd?

If you have a floppy disk you can put the PLoP bootmanager on it:
http://www.plop.at/en/bootmanagerdl.html
This bootmanager has USB support and can boot from an usb stick even though your bios does not support it.
You can also burn PLoP on a CD. This is good if you want to burn only one generic CD and then be able to boot any usb stick instead of burning one cd for each OS you want to boot.

Hello.. my hp dv6748us cannot boot from usb nor external harddrive.. may harddisk is already broken

hello.. my hp dv6748us cannot boot from usb nor external harddrive.. may harddisk is already broken so i bought i new one. my internal dvd drive doesnt work also.. can anyone help pls.. thnks

Is USB boot enabled in the bios, it should be able to boot from USB.
Other than that you will need a working DVD drive.

T61 cannot boot from USB harddrive

My T61 cannot boot from USB harddrive. the drive have VID 058F and PID 6391, the drive is bootable on all other computers. What happened? The bios does not recognize the drive at all.

cwang36, welcome to the forum,
I've had some strange experiences with usb hard drives and would ask you to try the following; when you want to boot from the drive start your T61, go into the BIOS > Startup > Boot menu and you should see the option USB HDD with a "-" in front of it. If I am correct you should exit BIOS, (F10 save and exit), upon restarting enter BIOS again and go again to the Boot menu. This time the USB HDD entry should have a "+" infront of it showing that the drive has been properly recognised.
If my theory is correct, no guarantees, you can then exit Bios with F10 and hopefully boot from the drive.
Hope this helps.

Satellite C50-A-1DV - Cannot boot from USB

Satellite C50-A-1DV PSCG6E-08P01CEN
I could previously boot from USB by selecting Secure boot to off and CSM boot in the system bios. Since I have upgraded my bios from 1.3 to 1.4 I can't seem to boot from a USB drive. I can boot from the CD but not USB.
Any Ideas?
Booji

hello
if you want install os in laptop then you should have to change the boot mode in BIOS menu.
for win 7 select the CSM boot mode
for win 8 select the UEFI boot mode
then boot by the pen drive and also CD/DVD.
Restart the system and hold the F2 key then you get your BIOS setup
if not get the BIOS setup by the process then you should tried power drainage.
Power Drainage process: just remove the battery and adapter of the laptop then hold the power key for 30 sec
after that connect adapter of the laptop then turn on system.
Try it...:)

Re: Satellite NB10T-A-101 - cannot boot from USB stick

Hello,
I bought a new Toshiba Satellite NB10T-A-101 and would like to boost performance by changing the HDD by a SSD and install windows 8.1 Pro.
I'm however unable to boot from USB, it always mention:
+Reboot and select proper Boot Device or insert boot media in selected boot device and press a key.+
I already disabled secure boot, used 5+ different usb sticks (work all fine on other laptops).
Can you please tell me what the approach is to change the HDD and then boot from a bootable (UEFI) usb stick.
Thank you.

Hi
The notebook Satellite NB10T-A-101 was equipped with an Intel N2810 CPU which is part of the new Intel Bay Trail-M platform.
This new Intel Bay Trail technology allows the installation of UEFI capable systems:
Win 8 or Win 8.1
Just few questions:
Did you already change the HDD to SSD drive?
If yes, is the new SSD drive recognized in the BIOS?
Did you try to boot from this Win 8.1 USB flash memory stick before you switched to SSD drive?

Cannot boot from USB-DVD on HP Envy 13

Even when the USB DVD drive is selected as the primary boot device or selected as boot device after pressing ESC and F9, I cannot boot from DVD.
According to another post I have:
http://h30434.www3.hp.com/t5/Notebook-Operating-Systems-e-g-Windows-8-and-Software/Boot-problem-but-...
I have problems booting from HDD as well, and now I also have problems booting from DVD. I have tried 3 different bootable DVDs.
Does anyone have any ideas to how the booting process could be corrupted any further and how I can regain the boot-from-DVD function? Now I cannot even run the recover DVD and recover the PCs factory settings.
However, I can still boot from HDD following the description from the other posting.
Thanks with best regards

Could you please give me the exact product number for your notebook?

W541: Cannot boot from USB created with Windows 8 create recovery drive

Hello, I have just bought a W541, and want to install the supplied Windows 8 on an m.2 SSD.I created the recovery drive on a USB following the instructions in the User Manual, but the recover image procedure under Advanced Options cannot find the USB.During the re-image step, it fails to find a drive with a valid image.I've confirmed using the command window available under the Advanced Options that the USB is mounted Searching these forums, I found the following, which describes a similar problem for a T540:https://forums.lenovo.com/t5/ThinkPad-W-Series-Laptops/Lenovo-W540-won-t-boot-from-USB-flash-drive-ThinkPad/m-p/1500902#M39097 This implies that the USB should first be formatted with FAT32 before use, which cannot work, since FAT32 only has a maximum 4 GB partition, whereas when copied to the USB, the Windows 8 recovery drive occupies nearly 10 GB. Is it possible to specify the boot order from insde the BIOS? I could only find an entry under Security about UEFI boot enabling, nothing about the boot order. Can anyone help?Paul

Hello Z, thanks for the reply. I tried another USB drive, and created a recovery drive, as before.This time it was able to detect the presence of the drive when I tapped on the Enter key when starting up, followed by the F12 key. However, there are still problems when I clicked through the options:Choose the languageChoose your keyboard layoutTroubleshootAdvanced optionsSystem Image Recovery At this point I am offered the option Windows 8.1.When I select this, it indicates it is scanning for system disks, and then displays the the pop-up window "Re-image your computer": "Windows cannot find a system image on this computer" Why does this happen if it detected that there was a Windows 8.1 installation on the USB? I've spent a whole day now on this. Luckily, if I can't solve it, the machine is new and I can send it back to Lenovo, and ask to have it re-imaged with the downgrade option to Windows 7.

T520 cannot boot from USB?

I just got the latest T520-4242
I want to use a kind of system installation or maintainance tool in a USB flash driver to boot my laptop.
The USB flash disk is a SanDisk Cruze 8G, but when I enter F12 at the beginning of the boot period, the menu of the boot option cannot recognize this flash disk. I've tried several computers to boot from this usb disk, they all booted well.
I have another USB flash disk SanDisk 8G, it can be recognized during the boot menu option. So it's very weird.

hey icenimbus,
now that is strange since a different flash disk of the same brand and size could be recognized.
is both of them "cruze" or different? have you tried with different USB ports ?
if it is possible, load up your unit and get into the bios and set it to boot from USB only . See if this makes and difference and do try with a lower capacity flash drive.

Cannot boot from USB HD on T61 & T61P Why not?

Have bootable WD and Hitachi HDs in external USB enclosures. Have successfully cloned one of these WD) using Acronis. When trying to boot from the USB attached drive using PF12 and selecting the recognized drive on the boot menu get either BSOD or message unable to boot operating system. What gives? Know the WD will boot internally as it was the disk that came with the system. Get the BSOD with this disk in USB port.
Hitachi give me the unable to boot operating system message when trying to boot from USB drive.
Using a TrekStor HD enclosure pn D260U20P10-3 which works fine if I boot the internal HD. Can copy and even backup internal drive to external HD but can not boot from it.

Hello,
As I understand it, Microsoft Windows 7 and earlier operating systems do not support booting natively from a USB Mass Storage Controller interface. The installers do from things like USB-attached optical disc drives and flash drives, but that's not the full operating system.
Support for booting from USB in the main operating system environment might be introduced in Windows 8—I thought I read something about this, but cannot seem to find a reference right now.

[SOLVED] Cannot boot from raid1 after upgrade

My system cannot boot from software raid(1) after upgrading the kernel to version 3.2.13-1. I realized then, that mkinitcpio.conf was overwritten (probably missed that in a previous upgrade). So I put back "mdadm" to HOOKS and "raid1" to MODULES. Unfortunately it didn't help. This is the boot-up screen:
Any ideas?

Thank you for your answer. I replaced the mdadm hook with mdadm_udev and updated my mdadm.conf. Removing the hd configuration stuff from grub then finally did the trick. Works again!
