IdeaCentre B350 - PXE no boot menu

Lenovo,
No PXE Boot Menu.
In BIOS I have set the computer to use PXE ip4 and ip6 to boot from the network. I have also tried disabling ip6 PXE in BIOS, yet I have no menu during computer start-up to boot from PXE. While the computer is booting I press F12 and there is a boot menu, but only the hard-drive is available, no PXE.
Anyone have any Ideas?

hi ttricktt,
Welcome to Lenovo Community Forums!
Boot the system in BIOS (Turn the system ON and start hitting F1)
Go to the EXIT TAB in BIOS and look for OS Optimized or OS Optimization and disable it or select other OS
Also Look for Secure Boot under Start up or Security TAB and disable it.
Also Go under Devices TAB and look into Network SET UP and make sure the LAN Boot Agent is enabled
Save and Exit
Now try booting in to the F12 menu again and check if the
Hope this helps

Can't remove PC-DOS from Windows 7 Boot menu after using PC-Doctor for DOS Bootable CD

I have a T60, Win 7 Pro
I had some issues and tried the PC-Doctor for Dos bootable CD to run some diagnostics. Since then, upon bootup, I have a PC-DOS option in my boot menu that just won't go away.
Using EasyBSD, the only os supposed to be in the bootloader menu is Win 7, yet, everytime I boot up, I get the boot menu.
I even tried using bcdedit to sstop displaying the boot menu but it still appears (for a split second).
Looking for some help in steps to remove the PC-DOS option from my windows 7 boot menu.

Hi,
I have tried something like that with ZenWalk (Slackware- based distro) and it worked for me on my Lenovo b305 with ATI 5450, no problems like that. Not sure about how Ubuntu will deal with these AIO systems. But I have a feeling that it is not your HD or booting, sounds like a video problem. ATI and Linux don't get on well.
Can you see the console y Alt +F1? perhaps you have to reconfigure Xorg manually.
My advice is to ask in Ubuntu forums they might have better ideas. ATI 5??? line is still "new" for Linux and the open drivers need time to work properly.
Also keep in mind IdeaCentre was not build for Linux...Issues like this might happen also post install.
Hope this helps,
Sergio

W520: Unable to boot from USB - device does not show up in boot menu

I have a W520, and I am trying to boot from a USB key. The USB key is bootable, my old T61p boots just fine from it, and so does another computer I tried.
The W520, after pressing F12 on power on, immediately shows the Intel PXE agent and then some blue boot menu, which only shows hard drive and LAN as available boot options.
I have tried all three USB ports but the results are always the same - the USB device does not show up. Is there any trick or BIOS setting to enable boot from USB?
Thanks,
CS

Hello Neil
Thanks for getting back to me
The issue was that the usb drives were disabled in the bios from the Startup menu.
To enable
1. Enter bios
2. Select boot
3. If you do not see the boot device you require use the down cursor key until the "Excluded from boot priority order" becomes visible.
4. Select the device you require (in my case USB HDD)
5. Save and exit.
You can now boot from a usb stick and install the Linux distro of your choice :-)
Cheers

Yoga 3 Pro - Accessing BIOS, boot menu and System Recovery

The following tutorial will explain the following topics
How to access the BIOS Setup
Choosing a boot menu
Start a system recovery
It is not the idea to explain every single option of the above, since many of them are complex and it would be too extensive for such a tutorial like this.
To execute any of the tasks above you need to press the button marked with the red arrow in the picture below:
Press the button when the Y3P is off! Use a small pointing device, I use the tablet pen of one of my Thinkpad tablets
Once you press the button you will be presented with the following screen:
Use the cursor keys to move up and down, press Enter to choose an option.
1) BIOS Setup
The BIOS is where you can get technical information about your device, as well to change boot parameters and setting up security passwords. Be very careful when changing certain values, since it can affect the way the Y3P works and/or affect performance and security settings.
Information Screen
It gives the hardware details of the Y3P, like CPU, installed RAM, SSD capacity and so on. This is a display only screen, no settings can be changed here:
Configuration Screen
Time and date can be changed in this screen. Furthermore to deactivate the Wireless LAN and enable the Intel Virtual Technology. If you plan to use Virtual Machine software in your Y3P this setting must be enabled
Passwords can be set up in this section. Secure Boot settings can be changed here.
Primarily designed to protect users from rootkits and other malware attacks by blocking unauthorized executables and drivers from being loaded during the boot process, it must be deactivated if you plan to install Linux or having paralel operating systems
Boot Screen
Boot modes can be selected in this screen, you can disable booting from a USB stick or from a network for example
2) Boot Menu
This option is useful if you have Linux installed (using managers like LILO, GRUB, etc).
If you only use Win8 or higher there 's no much you can change.
3) System Recovery
This option will allow you to restore the system to either its factory setup, or to a previous backup done within Windows
A factory set up will leave the Y3P as it was shipped from Lenovo your private data and installed apps and/or programs will be wiped out. So make sure you have an external backup before such a reset

OK article. Doesn't answer my questions.

Lenovo G580 boot menu is not working when pressing F2 and F12 key

QuestionI bought a new Lenovo G580 series laptop. After installation of Windows 7 Ultimate x64 bit edition, a problem revealed when Lenovo driver get installed.
When I installed Intel HD 3000 graphics driver and restarted laptop, the Window was unable to start normally. It displayed an error, so a recovery program started which was recommended. But this program failed to resolve the problem. Later, I tried again to load Windows normally but the blue screen fatal error showed up.
I attempted to reinstall Windows again, but after restarting window, the boot menu was not showing up after pressing F12 key. F2 key was also not working either.
I spoke to a Lenovo techincal assistance expert and they suggested me to remove battery and charger and press start key for 30 seconds.
My problem still remains the same, and I am unable to access boot menu.
The bios version is 62cn34ww. ls there a way I can get this running again?
AnswerPlease take note that the suggestion below is just a troubleshooting guide. If the steps could not fix the issue, you need to send you machine in for service for further assistance.
Try removing the hard disk , then press F2 button to enter BIOS
If you are successful in entering the bios, pleaes load set up defaults
Save setting by pressing F10 and shut the machine down
Connect the hard drive back and check if can enter BIOS via F2 and F12 to see boot menu

"OK, I will retain my sanity.... changed & of course forgot windows 7 password on my Lenovo H430 desktop. (about a month ago) came accross my windows disc & was going to see if I could boot from it (wouldn't from the pasword unlocker i downloaded) Anyhow, i evidently have a password to enter bois setup which i attempted to "guess" baaad idea. i am now looking at Fatal Error.....System halted on my Lenovo H430 desktop. how do i proceed without doing any damage???

Windows 8.1 flex 14-2 boot menu direct to windows no usb or bios setting start up

Windows 8.1 > yesterday suddenly to make a selection from more boot menu ; ( Fn - F12) He takes no bios setup or a USB boot stick more but starts right after selection windows again? These have put a lenovo flex 2-14 with a self built-in SSD 250 840EVO disk where I am in the bios Boot UEFI mode to Lagacy support. Via de novo button I can still get into the bios and change the settings here ; Boot menu ; legacy support boat priority ; legacy first USB boot ; enabled All updates are automatically done so I suspect something has changed what is causing this problem?

Latest Bios installed.
Bios Priority; usb stick firts, SSD drive last.
Still direct from boot menu to windows

Laptop won't load OS, won't enter BIOS/Boot Menu.

I recently installed Windows 7 Professional on my Compaq CQ56 PC, on a 260Gig HHD partition. I then installed Opensuse linux on the remainind 60Gig. However half way through installation my PC ran out of power and dhut down. I tried booting and changing the Boot Device menu, so that I complete installation, but it won't allow me to go into the boot menu (simply stops on the compaq start screen - fan and cd-rom will be working.) Is there a way for me to rectify this without losing my data?

It sounds as if you were never warned to always do an OS installation or anything that has to do with partitioning while on external power.
Please identify your notebook with more than just the model type. You have given an incomplete picture of your hardware configuration while reporting an extreme hardware/firmware issue. IT would help to remove the battery and take a look at the service tag. Please post the p/n (product number) here in your thread
There are a few things to try.
Remove the hard disk. Connect the power adapter and press the power button. Does the BIOS screen appear and warn that it can not find a bootable disk?
If it does not, then try a hard reset.
Try a hard reset as follows:
1) Remove the battery and unplug the DC power adapter.
2) Press and hold the power button for more than fifteen seconds.
3) Plug in the DC power adapter (leave the battery out for now)
4) Press the power button
Please post your positive or negative results here in your thread.
You can put the hard disk in an external housing and connect it to another PC to try torecover your data. What you will see will depend on the operating system of the PC that you use for data recovery.

[SOLVED] Using Apple's UEFI boot menu with Arch

Hello,
I've successfully installed arch on my mid-2012 (5,1) 11" Macbook Air, and now I'm trying to get an entry in apple's boot menu (the one that shows when you hold 'option' when starting the computer). From the author of rEFInd's install instructions (http://www.rodsbooks.com/refind/installing.html#osx) it sounds like I can just add some files to `/dev/sda1` (a vfat directory that contains the stuff needed to boot macos), and then run apple's `bless` command and we're good to go. Unfortunately I've tried this a bunch of different ways, to no avail. I think some of my failure is simply because of a misunderstanding of UEFI, here are some questions I (partially) don't understand and my current understanding of them:
1. Do I even need a bootloader on a pure GPT/UEFI system? It seems like the answer is no, and I can just use the UEFI firmware and the linux kernel to load Arch (per: https://wiki.archlinux.org/index.php/UE … ux_Kernel). Note: I'd like to have as little software between the firmware and the os, for speed and simplicity. However, I'd still like to dual boot, but it sounds like the firmware can handle showing me a menu as long as there are entries pointing to parts of each OS.
2. Will grub/rEFInd/syslinux do some of the work for me initially/on a kernel update? I think the answer is yes, which would be motivation (esp when I need to update the kernel) to just use a multibootloader and have it handle arch and the firmware pass control to either that or MacOS
3. Will `efibootmgr` brick my mac? https://wiki.archlinux.org/index.php/UE … FI_systems says it will, but I think the `grub-install` command uses `efibootmgr`, so should I not try grub on here (this package: https://www.archlinux.org/packages/core … fi-x86_64/ ). Also some of the other packages (like rEFInd-efi) depend on efibootmgr, so does that mean any kind of an install from them (a command from the package, not the `pacman -S pkg` command) will also brick my system? (see rEFInd-efi dependencies: https://www.archlinux.org/packages/extr … efind-efi/ )
I've been searching a bunch of different things, output of the `bless` commands I've been running, and have found the following:
* https://bbs.archlinux.org/viewtopic.php?id=148647
* Using OSX to install rEFInd manually (moving the files around and using OSXs `bless` command) http://www.rodsbooks.com/refind/installing.html#osx , I used the rEFInd files from Archs repos: https://www.archlinux.org/packages/extr … efind-efi/ )
* The Wiki docs on rEFInd https://wiki.archlinux.org/index.php/UE … ing_rEFInd
To summarize, I'm trying to set up a dual boot between MacOS (installed) and Arch (also installed, there's just no way to boot it on my system yet) using Apple's built in menu that deals with the EFI partition on /dev/sda1 . Thanks in advance for any help!

Not quite. That makes a boot loader bootable, but it doesn't add an entry to Apple's boot manager menu. There's a blog post somewhere by Matthew Garrett that describes the steps necessary to add something to Apple's boot manager, but I couldn't find it in a quick Web search. Maybe you'll have better luck, or be able to track down the same information somewhere else. As I recall, it involves using a separate HFS+ volume, creating two or three dummy files, and using "bless" in OS X.
1. Do I even need a bootloader on a pure GPT/UEFI system?
Yes, you do need a boot loader. It's important to distinguish between a boot loader and a boot manager, though. The former is a program that loads a kernel, and perhaps associated data, into memory and transfers control to the kernel. A boot manager presents a user interface that enables you to select which OS (or which boot loader) to launch. A boot manager is not strictly necessary, and Apple's EFI implementation includes its own simple boot manager, which is what you've been unsuccessful in configuring.
Note: I'd like to have as little software between the firmware and the os, for speed and simplicity. However, I'd still like to dual boot, but it sounds like the firmware can handle showing me a menu as long as there are entries pointing to parts of each OS.
Many people make do with the firmware's own boot manager, but this can be rather inflexible. I'm not even sure if Apple's boot manager can handle passing options to Linux kernels' EFI stub loaders. This ability is not absolutely required, but without it you must compile your options into your kernel at compile time, which greatly reduces flexibility since you can't modify the options on a per-boot basis -- say, to boot into single-user mode if this is required.
2. Will grub/rEFInd/syslinux do some of the work for me initially/on a kernel update?
The usual Arch Linux method of handling kernel updates is to overwrite an old kernel with a new one, so no boot loader/boot manager changes are required. If you want to keep numbered kernels around (as most other distributions do), GRUB provides scripts that can help automate changes, but they are required in the grub.cfg file. rEFInd can auto-detect boot loaders, and if you're using the EFI stub loader, that means that the kernel is its own boot loader, and with a proper configuration, rEFInd can detect new kernels without changing its configuration file.
SYSLINUX has some very early and very experimental EFI support. The one and only time I tried it (about a month ago), it wouldn't compile for me. (I don't know of a precompiled binary available on the Web -- the support is that new!) I don't recommend trying it unless somebody who's gotten it to work offers to help you personally.
3. Will `efibootmgr` brick my mac? https://wiki.archlinux.org/index.php/UE … FI_systems says it will, but I think the `grub-install` command uses `efibootmgr`, so should I not try grub on here (this package: https://www.archlinux.org/packages/core … fi-x86_64/ ).
There were reports of efibootmgr damaging Mac firmware several months ago (I believe over a year ago). Since then I've seen claims that this problem has been fixed with recent kernels (3.0 and later, IIRC), but I've seen no substantiation one way or the other. Overall, I recommend caution....
Also some of the other packages (like rEFInd-efi) depend on efibootmgr, so does that mean any kind of an install from them (a command from the package, not the `pacman -S pkg` command) will also brick my system? (see rEFInd-efi dependencies: https://www.archlinux.org/packages/extr … efind-efi/ )
On a Mac, I recommend installing rEFInd (or any other EFI boot loader) from OS X rather than from Linux. (Note that I'm rEFInd's maintainer, so that's an official recommendation from the software's developer.) Offhand, I don't know if the Arch package for rEFInd runs efibootmgr automatically on boot or just has it as a dependency because efibootmgr is the usual way to register a boot loader on UEFI systems. If the latter, it should be safe to install the Arch package for rEFInd, copy its files, and then reboot to OS X to run bless on it. It would be just as easy, if not easier, to install it completely from OS X, though.

Windows 7 hangs from boot menu

Hi,
my Windows 7 partition refuses to start from boot menu, system just hangs and does nothing. I've not made any changes to the disk layout, only thing I can think of is the upgrade to 10.9.4 which probably changed the recovery partition.
History:
- iMac Mavericks 10.9.3 with boot camp 5.1.2 and Windows 7, used to start into Windows by pressing Alt on start up, then reboot from Windows menu or from Windows boot camp application into OS X and back without problems
- installed the 10.9.4 Build 13E28 upgrade some days ago
- Change today: rebooted from the boot camp system tray app into OS X, worked without a problem
- reboot from OS X into boot menu, select Windows 7 partition, system hangs
I've found this thread, describing a similar problem Repairing Boot Camp after creating new partition I think, however since my Index output only lists 4 partitions I think my problem might be a bit different.
Here's the output from: sudo gpt -r -vv show disk0

I guess something mixed up the MBR since I would have expected line 4 of the fdisk output to show something 'Windows' like instead of HPFS/QNX/AUX, but even if that is correct, the question is how can the boot problem be fixed?
The Windows partition is accessible from OS X, so copying the data is not a problem if everything else fails. As far as I remember, the boot camp version in windows is 3.3 (it's an older iMac model).
GDisk is available, command line not a problem, if you need any further info let me know, any help appreciated.
thanks,
jk

Hi,
> Does the Bootcamp partition show up in Finder and can you see files in it?
Yes, the partition shows up in Finder and I can see and copy files.
> In Disk Utility, does the Bootcamp partition report as NTFS?
Yes it does, "Get Info" from Finder also reports it as a NTFS volume.
> Do you have any third party NTFS drivers?
Yes I have, Paragon NTFS tools.
> If you hold the ALT key can you boot into Windows?
No, system just hangs and needs to be rebooted via power-off.
> If you came from 10.9.3 to 10.9.4, the Recovery HD should have existed under 10.9.3.
Yes it did, I did a clean install from USB media when Mavericks came out, the Recovery HD is also visible - and has been - in the boot menu.
> The one strange part is that your volume says "Windows 7". Were any diskutil commands run to change volume names?
No, just a left click on the Volume Name in Finder and then change Bootcamp to Windows 7.

So, you think running the Windows startup repair will fix the problem? Is there something that I should be aware of in terms of interfering with the OS X partition?

OS X Mavericks not showing up in boot menu?

Hi,
I recently applied to the OS X Yosemite Beta program and downloaded and installed the Beta. I have a 1TB Hard drive in my MacBook Pro which is was partitioned in two partitions, one for OS X Mavericks and one for Bootcamp. I decided I wanted to keep my original partitions intact so I installed the Yosemite beta onto an external hard drive so I wouldn't affect my main system. The Yosemite Beta installed and booted fine from the external hard drive but when I rebooted my computer I was presented with option to boot into my Bootcamp partition or an OS X Yosemite Installer. I can boot into Windows fine but not OS X Mavericks. The OS X Mavericks partition is still intact but does not show up during start up. I tried using a third-party bootloader like rEFIt but doesn't seem to work. Any help would be greatly appreciated.
Here is an image showing my boot menu, the items in orange are my external hard drive with the Yosemite Beta on it.

Thanks for the reply, I managed to solve my problem by forcibly unmounting the install partition and booting into Bootcamp (My only option). From there I selected my OS X Mavericks partition from the Bootcamp menu in Windows and I rebooted successfully into it. For some reason it still wont show up in the boot menu but rEFIt now works and will detect it along with the Bootcamp partition

Optical Drives Not Showing Up in Boot Menu / HDD

Hi:
In order to boot from a DVD, you need to change some BIOS settings.
Please read this info for what BIOS settings to change so you can boot from a DVD:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c03736054&lc=en&jumpid=reg_r1002_us...
You should be able to use the disks on a new HDD as long as the storage size of the new HDD is at least as large as the one you replaced.

Equium A80-132: Cannot select options in advanced boot menu

I'm having problem with my equium A80-132 ...
When i boot it up, it keeps going to the page " windows didnt shut down properly.... Boot in safe mode,last good known configuration... etc..."
I know thats an operation system error, but the problem is that i can't select any options neither go to the Bios, using the keyboard F2 function...
Dont know if if something with the keyboard... even when i press the arrow to select an option, it wont move/work.
But it does restart when i press Alt+Ctrl+Del... for the reboot shortcut.
Anyone have any idieas??
thx in advance

Hi,
There is one situation where the BIOS will not let you select the boot menu (F12 on my Tosh) to select an alternate boot device (nor will let it you enter the BIOS configuration, F2). I think it will sound strange but I can guarantee that it is behaving so on a Toshiba P200 PSB6. This is when Windows is in hibernating mode (last shutdown was "go to hibernation mode"). Believe it or not but the BIOS will force to boot from your Windows internal drive and will ignore any F12 key to select the boot menu.
This is the very first time that I am experiencing that, for instance some other BIOS will let you boot from a usb flash disk whatever the state. I agree that it makes sense to protect your Windows filesystem, as if you decide to boot Linux from a usb key and write to the hibernated Windows internal HD (Ubuntu will not let you do so but some other Linux could accept to write to an hibernated disk), it could result in a total file system failure.
Hope it helps

BOOT Menu Access Tecra R Series

How the hell do you access the BOOT Menu on the Tecra R Series?
And why isn't this documented in the Operating Manual (Toshiba)?
Thanks

Hi
As far as I know boot menu is accessible if you press F12 at start-up.
Choose bootable device using up and down arrows and confirm with ENTER.
Check it out.
