X280 live booting ubuntu with secure boot

Q: X280 live booting ubuntu with secure boot

Hi,I have an X280 running windows 10, which has secure boot enabled. To boot to windows I enter my Bitlocker PIN. I would like to continue using bitlocker and secure boot for windows.I would additionally like to live boot to Ubuntu from a USB drive, using the additional storage on the USB as persistent storage - I don't want access to the main Windows hard drive or any internal storage at all, just to use my seperate ubuntu OS on the X280 hardware. Ubuntu 18.04 says that it has UEFI support, which I believe is required to boot in a secure boot environment. My approach so far:- I press enter during startup, to bring up the boot options menu, and then press F12 to bring up the boot order menu.- The boot order menu has PCI **bleep** at the top, followed by USB, followed by the internal Hard Drive.- When I select the USB option, the screen... 'flickers' once? And then still shows the same boot order screen. I don't seem to be able to load from the USB at this screen.- When I click the internal Hard Drive, the system then goes to boot from the internal hard drive - at this point it asks me to enter my Bitlocker Pin and then the Bitlocker Recovery Key, which is expected as the hardware configuration has changed. I can always remove the USB drive and then load to Windows as usual.So in short - any tips on getting Live Boot from ubuntu to work on an x280? Am I doing anything wrong?Thanks,Jaz My

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

For a little additional info - I've confirmed that my Win10 is installed in UEFI mode.

tl;dr Is the Thinkpad x280 flawless for Ubuntu 18.04? Hello. I recently acquired myself a X1 Yoga 3rd gen with the hopes that I would have a nice experience running Ubuntu.

Hello. I have bought X280 one month ago and the screen brightness fluctuates occasionally, about once every 2~4 hours, for a duration of 10~20 seconds. When it happens, the brightness level fluctuates for around 1~2% at a frequency of change around 10 times per second. This issue is more likely (but not always) to happen after waking up from suspend mode, and happens almost every day. I use lowest (1 out of 1515) or second lowest level of brightness (76 out of 1515 in /sys/class/backlight/intel_backlight/brightness) by pressing Fn+F5/F6 on X280. My previous machine, X201s, can run on a similar level of brightness without any issue. After doing some experiment, I found that reduce the brightness to 0 (backlight off), and increase to 1 (out of 1515), can reproduce this issue easily. Just wonder does there anyone running Linux and experienced the similar issue? Is it more likely a hardware design limitation, or a hardware failure? Note: Contacted Lenovo via online chat, unfortunately they cannot provide useful information because I'm not running Windows. Searched online but didn't find similar issue on X280. Thank you.Details as below:Screen brightness: lowest (1 out of 1515) or second lowest (76 out of 1515 in /sys/class/backlight/intel_backlight/brightness )OS: Ubuntu Desktop 18.04 LTSThinkShutter: webcam coveredPower supply: This issue can be reproduced with or without the power supply connected.

FIrst post here, hope you can all help me.

I recently installed Ubuntu using Wubi on my laptop, meaning I could run it from another hard drive without altering XP. It worked fine the first time, apart from the wireless card not picking up and working. Someone suggested reinstalling, so I did so. During the installation, something broke down and it froze, so i restarted. Since then, the laptop has gone past the initial start-up screen and then gone blank, apart from a blinking pointer in the top left hand corner.

I assume that the Ubuntu installation is corrupt, and so start-up fails when trying to dual boot, but I have found no way to get around this.

Due to this being a new-ish laptop, I have no floppy drive for boot disks, and a multitude of boot CD-ROMS have proved unsuccessful. The last I tried was a CD to boot into DOS, but from there, I found no way to access the D drive (second partition where Ubuntu, and only that, is installed).

Any help as to how to destroy any reference of Ubuntu and give me back control would be much appreciated! I'll try anything.

So I dual booted my laptop with ubuntu a while back and had no problems. But when I tried to do the same for a friend I somehow managed to get to the point where i can no longer boot into windows(10). The ubuntu install in fine and usable but there's no boot menu that prompts which OS to boot into and the one time there was a boot menu windows wasn't there. Only an ubuntu/advanced ubuntu and 2 options called something to the effect of a memory test. I deleted 2 partitions in order to be able to dual boot ubuntu which was a recover partition and another partition with about 500mb of space. I'm assuming the latter was the partition with the windows boot on it. The large partition with his files on it is still there. What's the easiest way to get back into windows?
 

A:Can't boot windows dual booting ubuntu

Yep....never delete partitions with out knowing what they are and whats on them.

You may be able to recreate the MBR using some 3rd party partition software or using the install media to recreate the MBR.

NOTE: It's never a good idea to dual boot Winidows and Linux on the same HDD....as the Grub overrides the MBR and you have to jump through hoops to boot into windows if you delete the Linux OS.

I have Ubuntu dual booting on Win7. After the bios load, is there anyway that I can make Win7 boot right away without selecting anything on the OS selection? The same way it would boot without dual boot...if that makes any sense.

If the above exists: Let's say I use Win7 all the time, but one day I decide to boot into Ubuntu. Is there a way that I can press a button, before Win7 loads, to make the OS selection come up?

I tried to make myself as clear as possible and I hope that you understand what I'm trying to say.

Please ask if unclear.

A:Booting Win7 automatically, dual boot Ubuntu

Use separate HD's booted via the BIOS:

image or install Win7 to separate HD while Ubuntu HD unplugged,

set Win7 first HD to boot,

then if you want Ubuntu use the BBS key given on first boot screen.

So i two days ago i installed Ubuntu on my Secondary hard drive. I already had windows 7 installed on my primary drive. When i installed Ubuntu i didnt realize it at the time but i installed GRUB over Windows Master boot record on my primary hard drive that has windows installed. GRUB has been working but i wanted to restore my Windows MBR on my primary drive and have GRUB only on my secondary drive, and then if needed i could switch back and forth via the bios. As of right now i have NO Master boot record. At least not a functioning one. I am getting the error : Missing Operating System every time i turn my pc on. I tried using my windows 7 installation disk and repairing my computer, unfortunately when it shows a list of operating systems it isnt showing anything. I can then go and try to load a "device driver" while in System Recovery Options and i can indeed see that my hard drives are not at all formated. I still have windows installed. Also when i run the command prompt from system recovery options i can run fixmbr and other similar commands which say that they recognize windows is installed on a hard disk but having some kind of issue with the drivers for my hard disk. So i tried to FixMBR and then i now think, im not sure, but i would think i need to get the drivers for my Hard disk, or hard drive and install them in system recovery options.

A:Dual Booting Ubuntu Bad Master Boot Record (MBR)

Obviously you'd need to start Win7 to be able to add EasyBCD which can configure a Windows Dual Boot with Linux distros.

The problem is that GRUB can corrupt Win7 beyond Repair when on the same HD, so using a separate HD is always a better option if you can do so. In that case, unplug the extant OS HD to install the new OS, then boot your choice via the BIOS Boot order or one-time BIOS Boot menu.

Now as to repairing your Win7. First mark Win7 or it's 100mb System Reserved (preferred) partition Active: Partition - Mark as Active (Method Two)

Next boot into DVD or REpair CD to see if it will now discover a Win7 installation. If not, click through to Recovery Tools list to open a Command Line to run bootrec /fixboot and bootrec /fixmbr then reboot.

If Win7 doesn't start, boot back into DVD/Repair CD to see if installation now shows up to accept offered Repair. If not run Startup Repair - Run 3 Separate Times anyway.

You can copy out your files using DVD/Repair CD this way: Copy & Paste - in Windows Recovery Console or using Paragon Rescue CD.

You can see your partitions graphically and mark Active using free Partition Wizard bootable CD. Then click on Win7 HD to highlight it, from Disk tab select Rebuild MBR, OK, Apply to see if this will start Win7 which may preclude the need to run Repairs. If not, you can wipe the Ubuntu partition by rightclicking>Wipe. Now try the Win7 repairs again without the GRUB code on the HD.

If all fails, you'll need to try ru... Read more

Hi! So this is my problem, I had an image of my disk and I tried to boot it up from my VM workstation but it failed. I added in the line firmware = "efi". I used to be able to boot up without a problem in VM with my disk images before I changed to a new Win 8 laptop. So I was wondering does the secure boot somehow affects it? Would appreciate help on this!

A:Does secure boot affects booting up in VMware?

I have Player not Workstation so don't know if there is a difference but I have secure boot turned on and have no problems. From what I know, VMWare runs entirely within Windows so I don't see how secure boot would have any affect.

And welcome to the forum!

Edit: If you are talking booting from scratch with a VM image that is a different story. I will bow out as I have zero experience with that.

Hello everyone!

I've made my Sony VAIO into a dual-boot machine (Win7 64-bit and Ubuntu Linux) and I'm having trouble getting into the BIOS.

When powering up, even though I repeatedly press and hold down the DEL key it always goes straight to the GRUB menu:



And then when I select to load Windows 7, I keep pressing DEL but it goes straight to Windows.

It doesn't seem to matter how fast I am on the keys - I can't get into the BIOS.

I have a should I be trying to enter the BIOS before getting to the GRUB menu, or after?

Also, (and this may be irrelevant) I've checked my registry to determine what kind of BIOS I have (HKEY_LOCAL_MACHINE / HARDWARE / DESCRIPTION / System ), where I found that the SystemBiosVersion variable = Sony - 20110905 BIOS Date: 09/05/11 11:20:58 Ver: 04.06.03

(I would have thought the BIOS would be something like American Megatrends!)

Anyways... is there any way I can get into the BIOS from Windows, i.e. after Windows has loaded? Do I have to remove Linux from my computer? I hope not!

Thanks so much for your help and have a great day.

A:can't enter BIOS when booting (Win7 / Ubuntu Linux dual boot system)

Best to keep in mind that the BIOS is completely different from ANY operating system. There is no connection between the two things, other than the BIOS handing off control to an OS.

You press DEL (or whatever key enters the BIOS) before any operating system begins to start up.
You can start pressing the key repeatedly (once a second) just as soon as you hear the POST beep or see anything happen on the display screen.
Once you reach the Grub loader it is too late. Start over.

You can't get into the BIOS from an operating system. You can only shut down and/or restart.
Nothing in the operating system's registry has anything to do with your system's BIOS, other than communicating with it initially.

Hey there, I recently set up a wireless network. My friend in the same house running XP is able to connect using his laptop without difficulty with a less powerful signal.

I've also tried to diagnose the network with a tool, but I'm totally unable to connect to it so I'm unable to get any more information.

If I try to connect to an unsecured network, it works perfectly. I'm totally stumped about this, due to the fact that I've used two different operating systems, two different adaptors and two different laptops (albeit the same brand). Any help would be very much appreciated at this point.

I've gone into bios and secure boot is greyed out.

How do I get around this?

Running win 7 64 bit with an Asus x99-A motherboard. Specs updated below

What is your BIOS version? Have you flashed it?

Unfortunately as I have lack of experience with such an issue I can only refer you here:

I am aware it says "Windows 8" but just have a read through it and get back to us.

Hey all I am new here. I recently did a dual boot install of Ubuntu with my Home Premium Windows 7 machine. I need to figure out how to uninstall Ubuntu and the grub loader... any thoughts?

I installed Windows 7 first... Ubuntu 64 desktop edition came after.

I shrunk my Windows 7 partition to install Ubuntu.

If you need more information, let me know, and thanks in advance.

Hello Konstantinov, and welcome to Windows Seven Forums!

Baisically, you just need to delete the two Ubuntu partitions, then restore the bootmgr from Windows 7. Please look these over and post back any questions?

Hi,
 
I just bought the Thunderbolt 3 dock and remembered reading that you have to make some changes in BIOS for the usb hub to be detected in linux. So I entered BIOS and disabled thunderbolt security and enabled some other thunderbolt feature (the one below thunderbolt security, the tooltip tells you to enable this for linux support and older versions of windows 10).
 
After saving and rebooting all I see is a blank screen and the fans start going at full speed.
 
The computer does not boot into my OS and I am not able to enter BIOS again.
 
Any ideas how I can fix this?
 
Is there a way to factory reset the BIOS without entering it? Usual solution here is to remove the CMOS battery but I really don't want to open my brand new laptop unless I know my warranty is still valid.
 
Any help would be greatly appreciated.

A:ThinkPad X280: After BIOS update, notebook won't boot anymore

It is not very difficult to remove the CMOS/Coin Cell battery on that system, just remove the main battery, and then loosen 3 screws to open the large bottom cover (see page 73 of the ThinkPad E560 and E565 Hardware Maintenance Manual for details on removing the cover)    Once the cover is open, unplug the CMOS/Coin Cell battery (you don't actually have to remove the battery), wait a few minutes and then plug it back in (see page 81 of the HMM for details). Doing so will not effect your warranty, but don't force anything and keep track of the screws.

Microsoft has been attempting to patch a serious Secure Boot vulnerability that can be exploited to bypass the security feature and install rootkits and bootkits on Windows devices. Researchers believe the security flaw cannot be fully patched.

-

On systems where Secure Boot is locked down and cannot be disabled (e.g. Windows RT, HoloLens, Windows Phone), configuration changes can be made using policies, signed files loaded by the boot manager (bootmgr) from a UEFI variable. There are some boot loader executables (EFI files) signed by Microsoft that can be used to provision such policies.

Before loading a policy, bootmgr checks it to make sure it?s valid. However, researchers discovered that Microsoft introduced a new type of Secure Boot policy during the development of Windows 10 Anniversary Update (v1607) that can be abused to bypass the security feature.

I downloaded and burned Ubuntu 7.10 to a CD and ran it direct from the drive - good stuff!! Next I wanted to actually install it on my HDD permanently. I created some empty space on my second HDD and told Ubuntu to install itself there, which it appeared to do fine.

I rather naively expected that there would appear a dual-boot process with the Win-XP on HDD1, but nothing appeared and it just boots straight into XP as usual. So I download GAG4.9, create a booting floppy and set up the various boots, which GAG identified perfectly as a Linux partition.

Whilst XP boots as usual from the GAG booter, Ubuntu does not - I get a message saying

"sector boot not found or invalid"

Poking around with Partition Magic, I find the whole of the 2nd hard drive is declared to be 'bad', message is 'invalid extended partition'. Norton disk manager says it is invalid too. The odd thing is, two other partitions that I left on that drive (data backups), are still perfectly usable in Windows, and can still be seen in Partition Magic.

So apparently Ububtu has done something unexpected with the first partition, which makes the whole drive appear to be an invalid extended partition, yet the two extended partitions on there are still intact. Yet Ubuntu boot deos not work.

Can anyone shed light on what is wrong or what I should have done to get a working Ubuntu on my 2nd HDD ?
 

A:Ubuntu 7.10 on 2nd HDD not booting

How exactly did you tell Ubuntu to partition the second hard drive?

Ubuntu asked you where to put its bootloader. What did you say?

Try telling GAG to boot the second hard drive itself, not any of the partitions.

I cannot get ubuntu to boot from CD. I know the CD works because I used it before on an older machine.

I now have a laptop and desktop both already running vista.

Ubuntu will start the to boot. I select the keyboard and language ok. Then after the hardware scan it fails because it 'Cannot copy files from CD-Rom'

I tried updating the firmware for the Drives and still no go. I tried every command I could thing of to bypass the files that are making it stick.

Any ideas?

Hi All,

I never setup a triple-boot system before. I kind of have an idea of how I'm going to attempt this little project but wanted to see what you guys thought. I have a 320GB asus laptop and plan on using Gparted live cd to do all my partitioning. I plan to create 2 NTFS partitions and then create an EXT3 partition plus a swap partition.. is this the way or is their another/easier way?

Thanks All

After uninstalling Ubuntu a few days ago from my dualbooted pc, my computer doesn't boot properly. It loads the Toshiba logo, but before it actually boots into windows, it gets stuck on the grub bootloader screen. The screen says the following:

Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.



grub>_



I have a windows 8.1 installation disk, but whenever I put it in, turn it off and turn it back on, it waits a minute, but then it just loads the grub bootloader. According to the internet, its supposed to ask me what language I want and then I can fix it, but what am I supposed to do in this situation?

Whenever I turn on my computer, it goes to the Toshiba start up screen like it should, but before it goes away, another black smaller window shows up and it stops there. The black screen says the following

Pressing ctrl+alt+del just starts back at the Toshiba screen for a second before giving me the same screen as before.

A:Any One Duel Booting Ubuntu 12.10 With Windows 8?

My laptop is configured this way. I lost GRUB after reinstalling 8 over 7 (fresh install after getting the $40 upgrade ISO). I plopped in my livecd and did take some steps to restore my GRUB though. I used an online article to help me.

11.10 - Recovering grub after installing windows 7? - Ask Ubuntu The boot-repair answer here is what I went with. It worked.

But yeah, Ubuntu 12.10's partitioner is worded odd. I just went custom and manipulated my partitions manually. When I installed Windows 7, I already gave it a set size partition to start with. I gave Ubuntu a set size partition, and then the rest was left free for a big data partition. When replacing Windows 7 with Windows 8, I re-used the Windows 7 partition, but lost GRUB. I followed my link above to alleviate that. My laptop successfully dual boots windows 8 and ubuntu 12.10 as we speak.

I had previously had Vista 32 installed on my pc. I partitioned the hard drive, and installed Ubuntu 8.04 on the second partition. After that, Ubuntu became my default OS, and would boot in 10 seconds, unless I chose otherwise. Everything worked fine, with no help from me.

Yesterday I reinstalled Vista on the main partition, but didn't touch the others. Since then, there is no boot OS option, it automatically loads Vista. I can't figure out how to access Ubuntu even temporarily, let alone change my boot preferences to allow me a choice at startup.

Help is much appreciated
Chris

A:Dual Booting Vista and Ubuntu

You might try right-clicking on 'my computer' and selecting 'manage'. From there, go to disk management. Look at your hard drive and see if it is still partitioned. Vista might have copied over it. And, I found some info from the Ubuntu forum:

I have been running XP and Ubuntu, dual booted from separate hard drives using GRUB2 boot loader. No problems.
I wiped XP and successfully installed Windows7.
A problem has arisen in that whilst GRUB still boots Ubuntu OK, when I select Windows7 from the GRUB memu I get the Windows option to 'fix start up problems' or 'start windows normally'. None work.
I am fairly sure I have some sort of MBR problem. Under XP I could get a terminal via the install disk and just "fixmbr" and all was well.
Following the same procedure in Windows7 gives me an X:> prompt. fixmbr doesnt work.
Can anyone advise please how to fix the MBR in Windows7 ?
Thanks.

A:Dual Booting problems with Ubuntu

All former bootrec and bootsect commands are automated in Win7 Startup Repair. You only have to run it enough times for it to attempt to repair and then rewrite the MBR - usually about 3 separate times with reboot.

I believe that dual booting Win7 with Ubuntu requires removing GRUB before Win7 install and then reinstalling it.

I have a pretty nasty virus on my XP machine. It is from a torrented .exe that i ran. Thought I was safe after scanning the .exe and it's extracted .jars with MalwareBytes, MSE, AVG and Spybot. I guess not X(

I have been trying to remove files using updated clamav off an Ubuntu LiveCD. That found nothing. fpscan has found a bunch of stuff, but keeps failing when it scans.

Before I reboot into Windows to do the whole HijackThis (or I guess it's DDS/GMER now?) thing, I want to do as much as I can from Linux so I don't do more damage from Win.

Here are my questions. This is my work machine and I will probably be up all night trying to fix this before getting fired sometime tomorrow when I have to tell my boss what I've done .... I realize you guys go in order of appearance, so that probably doesn't make a difference to anyone here :)

1) I know procedure around here dictates that I run those and post the logs first. Is there a way for me to do this from an Ubuntu CD (I have internet access when in it)?

2) If not, do you have any other suggestions as to what I might try in Linux first (I'm going to try AVG if I can get it installed), or what might prevent fpscan from stopping it scan?

2-a) What about Ultimate Boot CD 4.11? Any suggestions on whether that's worth a shot or which built-in apps I could use for that?

3) Otherwise, is there any other forum you could direct me to where I could get some help in that area before I come back here?
