Windows doesn't boot after removing Ubuntu: grub black screen

I had Ubuntu and Windows installed in dual boot. I wanted to remove Ubuntu and, following suggestions online, I eliminated Ubuntu partitions. When I restarted PC I got this on black screen:
"GNU GRUB version 2.02beta2-15
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>_"
BIOS doesn't start so I can't boot from USB. I don't have factory image because I performed a clean installation when I installed Ubuntu and Windows.
I need help, thanks.

Hi,
as far as I know, Windows needs the bootableflag on it's systempartition - and sets this flag, in case it is not set - to boot up.
Actually, I don't know any way to prevent Windows from "touching" the MBR except a MBR-Lock (sometimes called "Boot-Virus-Protection") in BIOS - seems to be not possible on your configuration (Macbook -> EFI/GUID-MBR-Hybrid and not BIOS/MBR).
One way, to evade the drama of manually editing the MBR, would be letting the Windowsbootmanager load Grub.
1.) copy the grub-bootsector of your /boot partition to a file in your window-systempartition.
dd if=/dev/sdX of=arch.lin bs=512 count=1
mount the windows system-partition and copy arch.lin to the root of the partition (C:\ ?)
2.) adding a boot-entry to your windows-bootloader
boot windows, and add the line C:\arch.lin="arch" to the %SYSTEMROOT%\boot.ini
(this could probably also be done from linux while doing step 1)
3.) modify the windows-bootloader to fit your needs:
a) change timeout=0 to timeout=15 (or something like this)
b) let timeout=0 untouched and change the default to grub (so the boot-way should be: mbr -> windows-loader -> grub -> linux/win)
I am not 100% sure, if this works as intended. There are plenty of howtos on the internet dealing with the winbootloader -> grub stuff. maybe you should read one or two just to verify this.
Regards

HP G56 System Recovery Problem after removing disk 4 black screen

hi everyone
this is my first time, im helping my nextdoor neighbours laptop hp g56,

after the recovery system finished and told me to remove disk 4 it restarts and now have a black screen, does this mean its still installing because i turned it off and then on and now say no bootbale device.

The message means that your internal hard has been damaged. This message always comes up when the file system is corrupted. I suggest to remove it, connect the hard drive into a different computer as an external drive (use usb caddy), perform a backup if possible and the format the hard drive and restore the factory settings. I'm afraid that you have to reformat the hard drive, a checkdisk scan won't help..
The error message means that the Boot Sector is corrupt or has been damaged. It does not mean that the hard disk is damaged.
This is a fixable issue. There are a few command line tools that can be used.
You will need to make an appropriate version (32-bit / 64-bit) of the Windows 7 repair disc from a working Windows 7 installation. You will need either a USB or CD to create your rapair CD/USB. Follow the instructions on this video to create the repair installation of your choice..You will will be using the manual boot sector repair that is described in this video to repair your Windows 7 Boot sector. Use the Windows 7 repair disc or repair USB thumb drive that you created earlier to accomplish the repair.
Best regards,
erico

Mac doesn't boot after splitting BOOTCAMP drive under Windows 8.1

Macbook pro mid 2012, OS X Mavericks
I've installed Windows 8.1 x64 using Bootcamp assistant. In Windows I went to Disk Management and shrank drive C: from 200 GB to 94 GB and created a new drive D: from unallocated space.
After restart Windows doesn't boot giving some error and quickly restart. If I hold "Option" key I see only Windows. Mac OS X disappeared.
How to fix?

So, I've tried 1001 ways to recover. Nothing worked. Interned Recovery gives -2002F error. Macbook pro 2012 can't boot from bootable DVD to use DiskWarrior, Drive Genius or similar. It can't boot from OS X Lion install DVD. I had only Windows PC to fix this. So
I asked a friend with latest Mavericks(which I had too) to make a Recovery USB and make a DMG file from it and send me over internet. Then I used the TransMac application under Windows and burned DMG on my USB stick. My god it worked. After 2 days of struggle I found this solution. I was able to boot from this USB stick into Recovery Mode and from there I can reinstall Mac Os X Mavericks. Somehow it sees my Ethernet cable and doesn't give error.
Note: that Disk Utility wasn't able to recover partitions. I tried to run DiskWarrior from terminal but it gave me an error. TestDisk didn't run too. So I'm doing a clean installation.
I could recover or backup my files using Paragon Mac Recovery Bootable DVD, but there was no need since it's my new macbook and I didn't have much files there.
Windows had changed the HD partition map from GUID Partition Table(GPD) to MBR. And made HD a "dynamic disk". This is why Mac Os wasn't able to boot.
If anyone knows how to convert a disk back to GPD and make Mac OS able to boot please let me know. I'm still installing Mac Os X on USB stick and didn't change my HD.

Does your computer do or show any error mesages on the screen when rebooted. You did do this in DOS didn't you?

Apples update didn't work for me: Boot Camp: iMac displays a black screen during installation of Windows 7

Boot Camp: iMac displays a black screen during installation of Windows 7 - Apple Support
I have followed each of the steps listed in the link above with no success.
Prior to adding the extra drivers I was able to start the Windows install process up to reformatting the "Windows" Bootcamp drive. After that the computer would go through some instal processes and eventually restart. After the restart the screen would go black. The black screen lead me to the Apple Support link above dated March 5 2015. After going through steps listed in the link above, I get an error message stating that the D:\Sources\instal.win. file cannot be located. I am forced to restart the computer at that point and theWindows install process attempts to start again but always ends up at the same point.
Note: I am installing windows 7 Pro from a DVD. I scanned the AutoUnattend.xml file and noticed that it refers to "Windows 7 ULTIMATE" but not "Pro" or any others that I could see. (see below). Could that be part of the issue?
Any feedback would be greatly appreciated.

is telling that a retail product key will be entered, which should go look for this specific .clg file (from the five you already have on disk). You can test if it will work for you by changing this line to the following

Guide to Upgrading to Windows 8 on the T540p (+fix for brightness/black screen on wake)

Hello all. I recently received my new T540p running Windows 7. Although I probably would have qualified for receiving Windows 8 recovery media from Lenovo, I went ahead and did the upgrade myself since I had a copy of Windows 8 laying around (and because I'm impatient). I'm fairly tech-savvy and expected the process to go smoothly; boy was I wrong. I decided to write up this little guide after having a thoroughly annoying time upgrading in the hopes of saving someone else out there from the hassles I underwent.
NOTE: The most troublesome part of the whole process was figuring out why the screen brightness was no longer adjustable and the display would not turn on after waking from sleep (black screen) after upgrading to Windows 8. Skip ahead to step #9 if that's the issue you're having.
Step #1: Make a bootable recovery disc or USB drive
This is important in case anything goes wrong during the upgrade or you decide you despise Windows 8 and want to bring back Windows 7. The T540p comes with a recovery partition in the hard drive (like most laptops nowadays I assume) which allows you to completely wipe your computer and reset it to its original factory state (the same as when you first received your computer). This is normally done by restarting your computer and hitting the enter key to interrupt normal startup and selecting the recovery option from a menu. I wrongly assumed that I would still be able to conduct the recovery after installing Windows 8, but for some reason after upgrading I was unable to start a recovery from the recovery partition. Thus it's important to create a set of recovery discs or a recovery USB drive yourself BEFORE starting the upgrade. Lenovo includes a program which makes this step very easy; see this page for details: http://support.lenovo.com/us/en/documents/ht004960
Step #2: Uninstall certain programs BEFORE upgrading
I skipped this step because I forgot about it. I haven't noticed anything adverse (aside from the brightness/display problem which I assume is completely unrelated), but Lenovo does suggest to uninstall certain programs before upgrading so it's probably wise to do so. Here's the list:
    - DisplayLink Core Software
    - Intel(R) USB 3.0 eXtensible Host Controller Driver
    - Lenovo Solution Center
    - RapidBoot
    - ThinkPad(R) Bluetooth with Enhanced Data Rate Software
See this page for details: http://download.lenovo.com/lenovo/content/windows8/upgrade/think/notebook2_en.html
Step #3: Download and save wireless drivers to external media BEFORE upgrading
After upgrading, I discovered my wireless didn't work and thus I couldn't connect to the internet. I wound up downloading the wireless driver to my phone and transferring it to my T540p. You could also use an ethernet cable to connect to your wireless router or cable modem. But if you have a USB drive, CD, DVD, external hard drive, whatever, save yourself the hassle and download the wireless driver ahead of time. You will need to know the brand of the wireless device (Intel or Realtek); look it up in your email receipt or from the Windows Device Manager under "Network Adapters". Mine was Intel. After figuring out the brand of your wireless device, go to the T540p drivers page here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t54... Look for a drop-down menu that says "Component" and select the option "Networking: Wireless LAN" (LAN, not WAN!). The page will refresh to show only the wireless drivers. Select the Windows 8 64-bit driver that matches your brand (I'm assuming all T540p laptops are 64-bit. If I'm wrong, please correct me). Download that sucker and put it to on the external media of your choice to use later!
Step #4: Begin Windows 8 upgrade
You'll obviously need to have a valid Windows 8 key or purchase a copy of Windows 8 for this step. I had a valid Windows 8 key that had been used on an old computer which died (hence my new Lenovo), so I reused it. This requires Windows 8 to be activated by phone which isn't nearly as scary as it sounds. We'll get to that later.
There are two ways to do upgrade: use a Windows 8 installation DVD or download a web installer. I had a Windows 8 key from a previous web installation and went with downloading a web installer. If you have an installation DVD, just insert it and get started. If you prefer to download a web installer, go to this page: http://windows.microsoft.com/en-us/windows-8/upgrade-product-key-only I think product keys are tied to either Windows 8 or Windows 8.1, so select the one that you have a key for and download the appropriate one. If you're not sure, you may have to try both.
During the upgrade, you will be asked whether you want to download updates (I assume this updates the installer) and afterward you will be asked to enter your product key. For some reason, when I downloaded the updates my product key would get rejected. I just restarted the Windows 8 installation, skipped the updates and then my product key was accepted. I don't know if this is tied to the fact that I was reusing a Windows 8 key (again, which had been used on a now dead computer) but if you find your key getting rejected then you may find skipping the updates helps. If this doesn't work and you're using the web installer, try downloading the other web installer (e.g. if you're using the Windows 8.1 web installer and find the key is rejected even after skipping updates, your key may actually be for Windows 8 and you should try downloading the Windows 8 web installer).
The installation itself should be a fairly straight-forward process. There are lots of guides online in case things go awry. If you have any trouble or errors, you should hopefully have made recovery media for worst case scenarios where you need to start from scratch.
Step #5: Install wireless driver & connect to your router
You should now have Windows 8 up and running on your system, but no wireless. Now's the time to use that driver you downloaded earlier. Install it and you should now have wireless access. Connect to your router and get online so we can start some badly needed updating!
NOTE1: your touchpad/trackpoint/keyboard experience will be especially funky at this point. That's because the drivers for them haven't been installed. Normally the touchpad won't be active while you're typing, but because the drivers haven't been installed you'll notice you'll accidentally move the mouse or click while typing (e.g. when entering passwords). Not to worry: this will go away when we install the Lenovo drivers now.
NOTE2: your function keys won't work (adjust sound, adjust brightness, etc.). That's also because of the drivers.
NOTE3: you may notice your screen's brightness may not be adjustable even from the Windows menu. Again, that's also because of the drivers. Hang in there!
Step #6: Activate Windows
Now that we're connected to the interwebs, it's time to activate Windows. If you're completely new to Windows 8, here's where you go:
-move your mouse to the upper right corner then move down
-select "Settings"
-select "Change PC settings" at the bottom
-select "Activate Windows"
This is where you'll enter your product key. As I've said before, my product key had already been used on an old, now dead, laptop. Reusing a key requires you to do a phone activation. If you find your product key gets rejected, go to the phone activation option and follow the instructions. An important note: at some point you will probably be asked how many devices/computers you installed Windows on. The correct answer is "one"; if you accidentally give another number, you'll need to call again and start over. (I'm assuming you're not doing anything illegal. As far as I know, there's nothing wrong with you reusing your key so long as you're no longer using the old computer Windows 8 was installed on, e.g. when that old computer no longer works. But if you're trying to install Windows 8 on multiple computers and you can afford to buy a new copy of Windows 8, shame on you. It takes a huge team of coders and support staff to make a product like Windows happen; help them pay their bills by purchasing a legal copy of Windows 8. Students can even get a copy for less than $70 with proof of student status. http://www.microsoftstore.com/store/msusa/en_US/pdp/Windows-8.1-Pro-for-Students/productID.288769600...
Step #7: Install Lenovo-specific updates and drivers
I typically hate all the crapware and bloatware companies include with new laptops, but Lenovo does make some which are useful. Their system updater should take care of downloading the rest of the drivers you'll need instead of having to download them all individually (with one exception: the graphics drivers may require a separate download later). Download the system updater here and keep running it until there are no more updates to download: http://support.lenovo.com/en/documents/ht080136
Step #8: Install Windows Updates
Load up Windows Update and start installing. If you're completely new to Windows 8:
-move your mouse to the upper right corner then move down
-select "Settings"
-select "Change PC settings" at the bottom
-select "Update and recovery"
-click the "Check now" button to check for updates
-click the "View details" text link to see the available updates
-click the "Install now" button to begin installing immediately
(Yes, the Windows 8 interface is dreadfully unintuitive unfortunately. Watch some Windows 8 tutorials on YouTube if you find yourself having trouble. Already looking forward to the next version of Windows!)
You'll also want to download the Windows 8.1 update if you installed only Windows 8 (the update to 8.1 is free). The download is available from the Windows Store.
Step #9: Install graphics drivers (if you're having display problems: unadjustable brightness, black screen on wake from sleep)
As I stated earlier, this was the most frustrating part of the installation process. My T540p came with only an Intel HD Graphics 4600 card, but it seems some others include a dedicated NVIDIA card. Whatever updates were installed with Lenovo's System Updater and via Windows Updates didn't seem to do the trick. I even updated the driver with the latest from the Intel website to no avail.
The solution, at least in my case, was simple: go to the T540p driver's download page and download the graphic card drivers appropriate for your system. Go here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t54... Look for the "Component" drop-down menu and select the "Display and Video Graphics" option and download the Intel and/or NVIDIA drivers appropriate for your system. (I have no idea what the Intel Wireless Display driver is for, so I avoided it thinking I don't need it)
BONUS Step: Go to ninite.com to download commonly used programs
Shameless plug for one of my favorite websites. It lets you pick from a list of commonly used programs, then downloads and installs each of them all automatically (and skips all toolbars/extra junk downloads). Makes getting started on a new computer a breeze!

Hello Yolanda,
a) I noticed that I can´t install MediaCenter on Win8, but just on Win8 Pro.
b) My problem is, as described, that installing "MediaCenter" on either "Win8 Pro" or "Win8.1 pro", though the "Media Center" key is accepted,
which I once 2 years ago downloaded on ANOTHER "Windows 8 Pro" computer, for free as it was a gift of Microsoft at that time - You could reserve = get up to 5 Media Center licenses per "Windows 8 Pro" computer for later use
on OTHER "Windows 8 Pro" computers - but never used ( i.e. NEVER USED FOR ACTIVATION ),
but after the first reboot, I am running "Windows 8 Pro with Media Center" WITHOUT LICENSE, as shown in the system screen.
Neither my "Windows Media Center Key" nor my "WIndows 8 Pro key" is then accepted to change the situation - I mean the keys I entered just before during the installation process of "Windows 8 Pro" and "Windows Media Center".
I am shure that I did not use the "Windos Media Center" key, as I have a list of personal keys I got for free from Microsoft, and I marked those 2, I used for other "Windows 8 Pro" computers.
So fact is, that with my brand-new computer, 32 Gigabytes of RAM, 4 Cores, "Win8 Pro" installed, I am forced to avoid the installation of "Windows Media Center", though I got valid licenses.
So your answer was not quiet helpful, as it does not change anything.
Sincerely
Rolf

Windows 7 won't boot after I installed GRUB

Hello,
I just installed Arch Linux on my laptop with Windows 7. I followed the Beginners Guide. However, when I did "grub-install --target=i386-pc --recheck /dev/sda" it said something along the lines of:
warning, no BIOS boot partition, embedding is not possible
warning, embedding is not possible, need to use blocklists
error, will not proceed with blocklists.
Now, I think this was my mistake. I decided to use the --force option. Now grub works, and boots to linux, but when I try to boot to windows, windows says Windows failed to boot.
Please help, and if I have missed any information then just ask me.
Grub version is 2.02 beta 2-4.
Grub is booting Windows, but Windows displays this:
Windows failed to start. A recent hardware or software change might be the cause.
Thanks a lot!

Actually, there already is an entry for Windows 7. It just doesn't work. Here it is:

else
search --no-floppy --fs-uuid --set=root AC66E08666E0529E
fi
chainloader +1
### END /etc/grub.d/30_os-prober ###
Also, when I ran gdisk, it says this: Found valid GPT with protective MBR; using GPT.
Can I just ignore that?
Thank you for your help!

Dual Boot, Windows doesn't boot.

Hi there,
Firstly, I'd like to apologize in advance if this has already been answered somewhere, but I couldn't seem to find it anywhere.
Yesterday, I tried to dual boot Windows 7 on my iMac with the latest version of Lion. I used Bootcamp and everything went according to plan untill I had to install Windows. My Mac restarted and began to install Windows, but after a while of installing, the disc stopped running and everytime I heard it trying to get back running, it was stopped by a weird noise, as if something was grinding onto it.
This kept going for a minute or two, when I decided to turn it off, since nothing was happening. After that, I started my Mac again and after a white screen, the only thing it shows is a black screen with a little type cursor in the upper left corner. I've tried to reboot it many times but I can't do anything, if I take the disc out, the only thing I get is a white screen, it doesn't go back to the normal Apple logo.
If anyone has some tips on where i should go with this, it'd be greatly appreciated!

You need to delete the boot camp partition and start over. Use Book Camp Utility or Disk Utility to remove the partition.
What happened is when you installed Windows and it did not finish installing the OS and will keep trying to boot to that partition and finish. Until the OS install is finished the Mac is flagged to boot automatically to that partition. This is why you are seeing the black screen.

Laptop do not boot after remove RTC battery !!!

After remove RTC battery for clear the power-on password.
my laptop is power on and fan is working but dont boot. just black screen.
helpppppppp

Polarity is really not an issue since there is a connector from the batery to the systemboard. It is either plugged in or not since there is a keyway at the header on the systemboard.

Comp doesn't boot after bios update

I flashed the new 1.90 bios using winflash on my K8N Neo2 Platinum, after the reboot my comp screen didn't turn on and ventilators stayed at max rpm.
I tried clearing CMOS (i know it can't do anything but it's worth trying) and using another stick of ram (PC4000 on hynix chips that can do cl3, my BH5 doesn't boot on cl 3)
but nothing helped.
Is there a way of reverting to the older BIOS?

Well it's hard to flash back to an earlier bios if your system don't post .
What you can do is to shut off system , remove +5vsby by turning off PSU .
Then remove all devices except the neccesary cpu/memory/gfx card/floppy drive (specially disconnect all USB ,including usb mouse/usb kb )
After having it barebone , reset cmos with the jumper (min 15.secs to be sure) .
Connect the power and see if it posts with a normal PS2 keyboard and no mouse.
If it does you can flash back with a msdos bootable floppy with awfl833d.exe and the bios file on it .

Just installed windows 7 Ultimate using Boot Camp. Problem is when I chose to boot the windows partition, I get the windows icon on the sreen showing that it is starting, but few second after I get a black screen

Just installed windows 7 Ultimate using Boot Camp. Problem is when I choose to boot the windows partition, I get the windows icon on the screen showing that it is starting, but few second after, I get a blank screen. I suspect a driver (screen) issue, since I also installed Parallell using the boot camp partition and that works fine.
Do anybody out there has an ideal of what to do to solve this issue.
Thanks

Windows 7 - Dont boot after install (Hyper-V)

Hi,
Today I was install a VM with Windows 7 Ultimate. The setup ran very fine, I've allocated 200GB in virtual HD and set 2GB to RAM.
After the install completes, a black screen appear and Windows dont boot (or start)...
Any tip?

Just ran into this same issue.
My problem got resolved after using the x64 version DVD of Win7 (just x64 instead of the DVD that had both x86 and x64 versions).
What I did:
My host is Windows 8.1
After installing Windows 7 x64 as VM on my 8.1 based laptop two days ago, I wanted to do the same on my desktop PC, but I had the same issue described here.
I used a DVD just with the x64 version for my laptop and a DVD with both x86 and x64 version for my desktop.
Tried repairing as advised by a post, but got the error: "This version of System Recovery Options is not compatible
with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of windows."
I exported and imported the VM from my laptop to my desktop to test it and it ran with no problems.
So I tried the DVD that had just the x64 version of Win7 and that installed without issues.
I'm curious if this happens only when a DVD with more than one Win7 versions is used.
