Booting into Windows with Unsupported Video Card

I'm looking to buy a Windows-only video card. I'm currently using the Apple branded 8800GT and want to use an nVidia GTX 290. If I change my target drive to my Windows partition, will the system boot normally into Windows if I only have the GTX 290 installed or will I still be required to have the 8800GT in place in order for the EFI to launch normally?

Set your sits on PC 285 maybe? Your 295 will require more power than available and has been a stumbling block for all that tried.

Trying to boot into Windows with no Windows Partition

So I tried Windows XP on boot camp and ofcourse it says it's not installed when it clearly is >_>
So I restored and when I boot up it tries to boot into windows, when it loads it says Disk Error insert boot disk. When I hold alt it only shows Macinstosh HD.
I've just re-partitioned and restored to Mac full partition again so I need to reboot and see if that works...
Any help?

The last line in your post says "I've just re-partitioned and restored to Mac full partition again so I need to reboot and see if that works"
Rebooting should take you to OSX provided you removed the BC partition correctly (using Boot Camp Assistant)
I am not sure what you mean by the rest of the post "So I restored" restored what?
It sounds as though XP was either not installed or not installed correctly, what happens now when you reboot?

X79A GD45 Slow start and slow boot into windows with SSD

Im having some major issues with my X79A GD45 board, When I start the system it takes about 30 seconds sometimes more for something to appear on the screen and from cold boot it starts stops and then starts again before loading.
Once its loaded it is taking forever to get into windows Im running 2 6gb/s SSD's in raid and the windows logo is able to appear and flash 3 or 4 times before I even get into windows.
Ive tried it with just a single drive and re installations of windows but get exacly the same thing its driving me mad as Ive spent so much money on this machine. Details of my system are below:
MSI X79A GD45 v1.0 Bios 1.6
Intel I7 3820
Corsair Vengeance 16gb 1600 Cl9
2 x GTX 680 in SLi
Creative Soundblaster 3D Recon Fatality Sound Card
2 x Sandisk Extreme 240gb in Raid 0
Silvertone Strider 850w PSU
LG Bluray Writer

Updated the SSD Firmwares and it made no difference. Ive already tried single drives and the same. The drives are installed into SATA 1 and SATA2 ports the 6gb/s ones. The hang time is atleast 20 seconds at the splash screen alone before loading into windows. I checked the event log for booting and this is what it showed:

Scene Window with Multiple Video Cards?

Hi,
I'm using the 3d Picture Control and displaying images using the scene window (the video hardware-accelerated window). The original video card was a Nvidia Quadro FX370 (PCI-express slot). I added a second video card, a Nvidia GeForce 6200 (PCI slot). Now the scene window will only render on displays connected to the second video card. When moved to a display on the original card, no scene is displayed and the window latches on to the background. Does anyone have any experience with this or have any suggestions?
TIA,
Joe

Hi Joe,
It seems as though there may be a conflict between the drivers for the two video cards. Since the video cards are made by the same company there may be some shared files between the driver and when they both try accessing the file it could be creating an errorous situation. The first step I would take is to ensure that you have the most up to date drivers for both video cards to verify that this situation has not already been fixed. Next to identify if your video cards are in fact sharing files:
Right click on My Computer and select properties to bring up the System Properties
Click on the Device Manager under the Hardware tab
Once the device manager is populated expand the display adapters and select one of your video card drivers
Right click and bring up its property window
Go to the Driver tab and click on the Driver Details to bring up all of the files the driver uses
Repeat steps 3-5 for the other video card driver and compare to see if it shares any files
Please reply and let me know the results of this process. This will help us to more specifically identify our issue.
Thanks and have a great night!

MAX shows PXI card when booted into Windows but not in Hypervisor mode

Hello again all you helpful forum-goers!
I'm having some difficulties with a Hypervisor system seeing the two Pickering 6 channel programmable resistor cards that are loaded into the PXI chassis. When I boot into Windows mode, MAX sees them under the My System just fine. When I then run the Hypervisor configuration software, I see them both listed, and have them assigned to the Real-Time OS. However, when I then boot into Hypervisor mode, MAX does not see them under the Remote Systems -> Hypervisor Target -> Chassis (or anywhere else), and the drivers report not seeing any modules either when I debug my code running on the real-time system.
Does anyone have any idea what setting or configuration I might have incorrect? Is there any other information I can provide that would be relevant or useful to answer this question? I'm not the main hardware guy, he just got married and so isn't available, so I'm out of my comfort zone. ;-) I write the software that runs on the system, though, so I'm not completely clueless. I know we just replaced the controller in the main chassis with a faster one (unfortunately I don't have the number on hand, the simulator is down in the lab), but I also know we are using that same controller and Pickering card on a different simulator and it is working just fine.
Any ideas? I very much appreciate your time!
-Joe
Solved!
Go to Solution.

Nevermind, the answer turned out to be that I did not have the drivers fully installed on the real-time system. Apparently that caused it to not recognize the cards. I never did figure out / remember exactly how to install the Pickering drivers on the real-time side, but fortunately I was able to just copy all the files that had "Pickering" in their name from the C:\ni-rt\system folder of the real-time file directory from another simulator to this one. ;-)
Cheers!

Hi, can anyone help with the problem I am having with pro book 4440s? I can't boot into windows 7.

Hi, can anyone help with the problem I am having with pro book 4440s? I can't boot into windows 7, nor can I enter the bios cause i fogot the password. the error I am getting says "windows failed to start. a recenr hardware or software change might be the cause. it then gives me options to boot from a disc but I can't do that cause I am unable to get into the bios to change it to boot from a disc.
The error message goes on :
File: \Boot\BCD
Status: oxcoooooof
info: An error occurred while attempting to read the boot configuration.
the only two options on the screen are enter=continue and ECS=exit
I just can't get pass this screen.
Please help.
Thanks

Hi,
If you don't already have one, use another PC to create a Windows 7 Rescue CD. Download the relevant ISO from the links below.
Windows 7 32bit
Windows 7 64bit
You should use an application such as ImgBurn to burn the ISO to a CD - a guide on using ImgBurn to write an ISO to a disc is Here. Once created, or if you already have this, tap away at the esc key as you start the notebook to enter the Start-up Menu. Insert the Rescue CD. Select Boot options ( usually f9 ), use the arrow keys to select the CD/DVD drive and hit enter. You may also get a prompt to 'Press any key to continue' - do this if asked.
When loaded, select Repair Your Computer and choose the Command Prompt. When this loads, enter the following commands and hit enter after each one - include spaces as shown.
Bootrec.exe
bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd
bootrec /fixmbr
bootrec /fixboot
Remove the Rescue CD and try rebooting the notebook.

IMac with bootcamp and parallel boots into windows 7 but won't boot into Mac OS lion?

Hi,
Thanks for your suggestion. Actually that was not the problem, because I had the Mcintosh drive set as my boot drive. The answer was that my Lion Os got somehow corrupted and I had to reinstalll Lion. This was all after I discussed the situation with the Apple Support people.

Genius needs to help! problems with my video card and system

Hey guys! I'm going to post my specs first so that you get a good idea of what I'm running on:
MSI Neo2 LS 865PE.....MAT=Slow
Pentium4 2.4C.....FSB=233=2.8C hyperthreading enabled ~>1.55V
Corsair TwinX 1gig PC3700.....memory on "AUTO" in BIOS with timings at 3,4,4,8 ~> 2.7V
Radeon 9700NP.....stock speeds ~>1.7V
AlienX case with 2 fan400 watt power supply and 6 case fans
Zalman Alum/Copper heatsink fan
1:I've had this motherboard for a few months now. I upgraded my video card from a nVidia Ti4200(128meg) to a Radeon 9800 a month ago, but I couldn't get it working at 8X AGP, no matter what voltages I threw at it. I returned it for a Radeon 9700NP hoping that it would work, but it still won't.
I'm using BIOS 1.9 and since there is no option to select your AGP speed, I could only try using ATI's drivers. Once booted into Windows, there is a slider you can move to select you AGP speed. On my machine It says that It has performed some tests and has concluded that AGP 4x is the best for my system....but my system supports AGP 8X!
I've moved the slider over to 8x (which requires a reboot) at least 5 times with each card but the slider refuses to move past 4xAGP after the reboot.
2: My second problem: I had an old stick of KingMax PC3200 and decided to buy 3 more sticks. Unfortunatly, the 3 I bought did not match the one I had, so I only put 2 of the new sticks I bought into my system. Immediatly, My system would crash, lock up, files were corrupt, and I got PLENTY of blue screens of death with a long message containing: 0x0000007 with all these other numbers and "0"s. I did a search online and found out I had a hardware incompatibility problem. I never got this with my old stick of ram.
I returned the 3 sticks of Ram and replaced them with the Corsair. Put my new Radeon 9700 in, formatted my hard drive....and within 24 hours, my system locked up 3 times, rebooted itself 5 times, and gave me the same BSOD as mentioned above with the same long message.
I didn't change anything except for the memory and the video card. I've been wanting to overclock, (thats why i bought the faster memory ) but I'm not sure what to do at this point.
I have my FSB at 233 but I'm scared to go any higher because of previous system instability at stock speeds. My RAM was running on 400 and MAT=Turbo with the most relaxed timings at 3,4,4,8.
I've given myself hours of sleepless nights formatting when my system wouldnt boot into windows; overclocking....etc. I NEED HELP. PLEASE. PLEASE. Anything could work at this point.
I'm trying to get more info on how to run my system at a 5:4 ratio, also.
If anyone has problems like me or knows what could be the problem with my system, please reply to this post, it would help me a lot. I've been trying to fix these problems for a few months now so anything is greatly appreciated.

Thanks a lot to you guys that responded. I brought my computer home this past holiday and I want to let you know where I stand as of now. I guess this thread is like my blog for my computer. I want to clear some things before my first post makes everyone confused.
1- I have only 2 sticks of memory in my system: the Corsair PC3700 TwinX 512x2
I returned the 3 KingMax I bought, and still keep my old stick just in case.
2- I am using the 400 watt power supply that came with the case. I read some reviews of the case and I know the reviewer did not have problems with the power supply. In my BIOS, there are some voltages it is weak on. Lets say: it it should be 5.00+, my power supply will be feeding it 4.96v or something like that, but I dont know, or think, that is a major problem...
3- My computer will refuse to boot if memory speeds are set at anything below 400. SO....if I want to use a 5:4 ratio and have to set my memory speeds to "333" in BIOS, my system refuses to boot.
4- This morning, I did manage to overclock my FSB to 250. Specs are as follow:
Memory Timing @3,4,4,8,4.....speed set at "AUTO".....MAT at "SLOW"
MY 2.4C's FSB was raised to 250 = 3.0gig
AGP/PCI frequency: 67.xx/3x.xx (cant go any lower)
CPU voltage: 1.5500
Memory voltage: 2.75
Video Card voltage: 1.7
Everything was fine for the whole day until I heard something click in my computer around midnight, and then seconds later, my computer froze and made a continuous beeeeeeeeeeeeeeeeeep. (you can imagine)
This "click" and system crash has been plaguing me for months now. I dont know whay it happens. I was just using AIM when I heard the click and my heart stopped.
My memory speeds have been set to "AUTO" even at the FSB of 250. But I don't know if this still means my system is at a 1:1 ratio. I know the BIOS then adjusts the memory to work at 500 if my FSB is 250...so I assume it is? I love 3gig, but somehow I feel that 2.8 is faster, since the FSB=233 running parallel to my memory, also at 233
A FSB of 250 is good enough for me, that's what I've been waiting 6 months for. If anyone knows how to set other ratios to achieve a FSB of 250+, please let me know, but as I said, my memory won't boot if its set at "333"

Unable to boot into Windows 7

Hello, today I was playing some video games inside of Windows 7, upon noticing that whenever the computer had an area that text could be entered, it would spam the space bar into that area. Ex. when i would hit the start menu, in the little text box that is for searching, the courser would move continuously across it, as if the space bar was being pressed. So I restarted. As normal when I heard the startup chime i pressed and held the option key to bring up the OS selection tab. But instead of bringing up the menu, it booted straight to OSX. (i tried this a few times with the same results). So I went into the bootcamp menu in settings on osx and selected windows as the startup OS. I then restarted. When the computer started up I was prompted to select Windows 7 to continue the boot process, so I did. It then went to the starting windows screen where it became stuck. I force shut down and tried again, but this time i tried to repair the disk in windows. The first time it failed to repair, then i did a memory test and when it restarted it worked. In windows i told bootcamp to use OSX as the startup disk and tried holding down option to go back to windows again, nothing, it went to osx. So in osx i went into the bootcamp menu in settings again, and selected windows and restarted. It got stuck on the selection screen in windows and i force shut down and tried again, but this time with with repair again. This time the repair was successful and it went to windows normally. So now it appears that i can only boot into windows by telling bootcamp that i want to boot into windows automatically. Holding down the option key does not seem to bring up the disk selector. I can verify that the option key does work because i tried 'command+option+esc" and it worked. any ideas on what the frik is going on?

Update! So apparently I believe the problem is coming from a few windows updates that are out. Whenever I repaired the disk it always uninstalled those updates. I repaired the disk again because it got stuck on bootup and when i logged back on it asked me to re install those updates. without them installed the option key thing worked again. So i guess i wont be updating this thing anymore...

Unsupported Video Card?

Hey guys I recently received my MacBook and I have just installed Windows Vista and installed Crysis to the Vista partition.
When I boot up the game it says:
"Unsupported video card!
'Standard VGA Graphics Adapter' [vendor = 0x10de, device = 0x0863]
Continuing to run might lead to unexpected results or crashes."
^^^So that pretty much means I can't run Crysis on my MacBook? That *****

Ah okay, I have the latest MacBook.
Would a game such as CoD4 run for example? Not that I really want to play lots of games on my Mac (I have my PS3 for that), I'm just generally wondering.

NF520T-C35 compatible with GTX460 video cards?

Hello,
to cut it short - I have problems installing Msi Cyclone GTX460 768MB/OC on this mobo. Until now I had Asus 9800GT which worked flawlesly. Preparation is done as usual (cleaning old drivers), vga in case, login to windows (XP Home, SP3), installation of new drivers (from MSI DVD that came with vga), restart... Then I came to the Windows logo screen, keyboard initialized but mouse NOT, and then after a few seconds - black screen. Fans are working, nothing I can do except for restart.
After that I can boot to the safe mode, mouse will sometimes initialize, sometimes not, but I can at least logon to safe mode via keyboard. I did other varants that came to my mind:
-deleting drivers in safe mode, rebooting, normal logon in Windows, then installing the newer ones from Nvidia site. After the reboot, exact the same hanging after Welcome screen.
-deleting drivers in safe mode, reboot to normal Windows, installing the older drivers (last ones from 9800GT) - no help, because drivers do not recognize 460GTX, and ask for a newer drivers
The usual suspect in this case is a power supply (Cooler Master 450W Real Power, 12A/10A at 2x 12V rails in continuity, 18A/16A at peak 60. sec), but I doubt that it is a problem - even if the supply is not strong enough for excessive 3D, it can at least have enough power to boot into Windows?
So, the only other explanation that came to my mind is that maybe my mobo is not compatible with GTX460 card? Why, because I found reports that some people needed to update mobo bios for GTX460 to work, but without any specific details about manyfactuter, chipset, etc. The latest bios is installed on my mobo, from May 2010.
Any help will be highly appreciated!

So I gave up on waiting for a miracle to happen, and bought a new motherboard (Gigabyte GA-M720-US3). Straight instalation, not a single problem, vga is fast as Usein Bolt... All the other components in rig are exactly the same, as well as Windows XP instalation (no, I did not reinstalled it), so it is pretty clear that for some reason MSI NF520T-C35 motherboard is not compatible with GTX460 cards. Is it a problem with this specific mobo or with a design of GTX4XX series, it is hard to tell - I have found many reports that people are having identical problem (hanging at a Welcome Screen) with GTX4XX cards from other manufacturers, on many different motherboards, in all MS OS's. But for the end user, conclusion is clear...
Big thanks to all the people who tried to help me! Problem not solved, rather overcomed.

No SATA drive after booting into Windows (BootCamp 5.0)

One of my DVD burners has failed in one of my 2008 Apple Mac Pro's. I pulled the drive out (it was PATA/IDE) and replaced with a new LG WH14NS40 Blu-Ray Burner. I had to pull the fan out (temporarily) and run a new 24" SATA cable (with right-angle connector) from one of the two extra SATA ports (on the motherboard) to the new actual SATA drive, and also install a MOLEX to SATA power connector.
I managed to get the drive installed (and working). I now at least have a Blu-Ray burner in my 2008 Apple Mac Pro (with OS X 10.8.3 Mountain Lion).
The problem seems to be with when I boot directly into Windows 8. When I boot into Windows 8, the two ports on the motherboard are disabled and the latest BootCamp 5.0 drivers don't seem to support the two SATA ports on the motherboard (they seem to be disabled). So when I boot directly into Windows, my LG WH14NS40 Blu-Ray drive disappears.
I really wish Apple would have just "done things right" from the very beginning and took the time to write decent BootCamp 5.0 drivers that supported the two SATA ports on the motherboard, so that users who need to replace their old/dying/aging PATA drives could easily replace them with SATA drives and use the two SATA ports on the motherboard.
Also it would have been nice if Apple would have taken the time to write good BootCamp 5 drivers (for Windows 8) that support booting from the two SATA ports on the 2008 Apple Mac Pro motherboard.
I've heard of many people that have tried installing RAID Controller Cards (from OWC) in their 2008 Apple Mac Pro to upgrade their four hard drive caddys from SATA II (3Gbps) to SATA III (6Gbps) but unfortunately the RAID Controller Cards don't seem to be bootable and the only option is to install a fifth (bootable) hard drive into the Apple Mac Pro and this is normally done by installing a bootable SSD drive into one of the DVD-drive bays. Unfortunately if you use a SATA SSD drive (which most SSD's are SATA) and then use one of the two SATA ports on the motherboard to connect it, then you go back to having the problem of not having a boot drive when you boot directly into Windows 8 (since there are no BootCamp 5 drivers for the 2008 Apple Mac Pro that support the two SATA ports on the 2008 Apple Mac Pro motherboard).
This seems to be a never-ending problem, and we have twelve 2008 Apple Mac Pro's (along with an office full of 2008/2009/2010/2013 Apple Mac Pro's) and we're getting extremely frustrated with Apple's lack of support in BootCamp 5.0 drivers for the 2008 Apple Mac Pro (and the two SATA ports on the mainboard).
Please fix this problem, and please update the BootCamp 5.0/5.1 drivers (for 2008 Apple Mac Pro users) and please support the two SATA ports on the Apple Mac Pro mainboard, and please make those two SATA ports on the motherboard bootable and usable in both Microsoft Windows 8 and in OS X 10.8.3 Mountain Lion. Please update the BootCamp 5.0 drivers to support the two onboard SATA ports in Windows 8 (so that my Blu-Ray burner is viewable/usable in Windows 8).

Just as a follow-up, yes it does seem to be possible to get both SATA ports on a 2008 Apple Mac Pro working (in Windows 8).
You need to enable AHCI in Windows 8.
First boot into Windows 8 and then go into the windows registry (regedit) and enable AHCI in your registry.
You can do this by going to the following registry key:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci
Set the "Start" Value data to "0" (to enable AHCI in Windows).
After AHCI is enabled in Windows, then reboot your computer and now the SATA drive (connected to the ODD port) should appear in Windows (under devices).
Now the next step is to update your AHCI drivers (in Windows) to the latest Intel drivers, so that your SATA device will actually work (and work properly).
The latest Intel RST drivers can be found here: https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=2101&DwnldID=2306 0&ProductFamily=Software+Products&ProductLine=Chipset+Software&ProductProduct=In tel%C2%AE+Rapid+Storage+Technology+(Intel%C2%AE+RST)&lang=eng
Download the 64-bit drivers (if you are running 64-bit Windows).
After you install the latest drivers, and perform a reboot, your SATA drive should now work under windows.
You can find a long detailed thread about enabling AHCI (in Windows 7) here: http://forums.macrumors.com/showthread.php?t=760482
The thread listed above is a bit old/dated (2009?) but it does give detailed step-by-step instructions for those that want to enable AHCI (and get those two onboard SATA ports working in Windows 8 or Windows 7).
I managed to get everything working in Windows 8, and I was able to enable AHCI in Windows 8, installed the latest AHCI drivers and I'm now able to use my SATA Blu-Ray burner in my 2008 Apple Mac Pro.
Hope this helps!

Can only boot into Windows 7. Can't even boot from Snow Leopard DVD.

I have no idea what prompted this. I don't recall installing any OS updates recently, other than some Windows Live apps in Windows 7.
I have an early 2009 Mac Mini with Snow Leopard, and have Windows 7 64-bit installed in a Boot Camp partition. When I installed Windows 7, I couldn't get the Boot Camp utility to install within Windows (I guess because it's 64-bit) so to switch back and forth between OSes, I just shut down the Mac and restart it with the Option key pressed, and select Mac OS X when I want to return to Mac. This has worked for about a month and a half now (ever since I got Windows 7). Suddenly I have problems.
I first had problems booting into Windows or Mac. I got to the grey screen with the Apple logo, with that spinning "progress" thing going for a while, then it would freeze up and get stuck on the grey screen with the Apple logo. I zapped the PRAM. No help. Then, after disconnecting all external drives (I have several) and extra USB devices, I was able to boot from the DVD install disk and reinstall Snow Leopard on my internal drive. Joy, or so I thought. Then I booted into Windows 7, and after some weirdness getting it to start, it did successfully start and ran just peachy.
Then I turned off the Mac and held down the option key (as usual) to return to Mac OS. But now all that happens is that I get a grey screen for a few seconds, then the Mac boots back into Windows 7, which seems to work fine. (I'm in Windows 7 right now.) I turned on one my external drives (Snow Leopard installed, connected via Firewire 800) in hopes that the Mac would boot into that, but same thing. Ignored and back to Windows 7.
Then I thought I'd boot from the install DVD again by putting it in the drive and holding down the C key as I restart, but the same thing--a grey screen for a few seconds, and then booting right into Windows 7. I can't seem to escape Windows 7! It's a bit disturbing when it won't even recognize the install DVD.
I tried to call Apple Care since I'm within my 90 day support window, but of course they are closed. I'm figuring that I'm going to have to take this into an Apple Store, but thought I'd see if anyone has any ideas. Any advice will be appreciated. Thanks.

According to Apple, Win 7 64bit is supported with Bootcamp 3.0. If bootcamp 3.0 is available; I could not find it anywhere on Apple's website. It appears the most recent version is 2.2. The only place I could find 3.0 is not on Apples website and it's a questionable source so I won't post it here.
It may just be a matter of time before Apple makes it available. I'm not suggesting you wait, however if the install disk can't be used, I'm not too sure where u could go from there. Calling Applecare might work.
If you do a simple google search using the terms 'download bootcamp drivers windows 7' u will see what I was referring too.
Here's what I found from Apple (It doesn't specifically mention 64bit however just win7): http://support.apple.com/kb/HT3920
This is not from Apple, but specifically addresses whether they support win7 64bit: http://www.macnn.com/articles/09/08/31/boot.camp.win.7.64.support/
Here is more info about bootcamp 3.0 and win7: http://www.apple.com/support/bootcamp/

Black screen when trying to boot into Windows 7

Hello everyone.
Today we've encountered an issue with one of our MacBook Pros with Windows 7 installed. The computer was booted into Windows 7 (it's strictly used as a Windows machine by this particular user) and after a time of inactivity it went to sleep. It wouldn't wake up from it's sleep so we tried a hard boot. At that point we would get the grey screen, the Apple tone wouldn't sound off and it would just go to a black screen (by default we have it booting to windows). So then we reset the PRAM. Now, we get the apple tone and we can boot into the Mac side. But when we try and boot into Windows, we get a blank screen.
What's even more interesting, if I try and boot into a Windows install disk to do a boot repair, it gives me a black screen. If I even try to boot from a live Linux cd, I get a blank screen! When important thing I then noticed was that the cd spinned for a couple minutes, then stopped. So I began to wonder if it was still loading the OS like expected, but just wasn't displaying it.
So I booted into Windows, got the blank black screen. Then I went into another computer, fired up remote desktop and voila! I'm in the machine!
So the problem is this: When booting into ANYTHING other than OS X, the display turns off.
What can we do?

Hello there,
I have a similar problem! Windows 7 shutdown unexpectedly and since that I can not reboot in windows anymore only with safe mode where everything is a mess.
Also when it's trying to reboot in windows a blue window appears,says something about drivers and it is counting something (79.78...till100)but I m not able to read it cause it disappears immidiately and then black screen and then it turns to reboot in mac which works fine.
I m sorry if I confused you with my english...
If anyone knows please help!
Thanks
