What's the difference between UEFI and Legacy and why can't I install Windows 7? I put the Windows 7 CD into the CD-Rom and the installation doesn't start up. It does start up only when I change the bios to legacy. What's the difference between UEFI and legacy? Is it possible to install it on UEFI? If not, if I will install it on legacy, will everything be ok?
I have a Acer Aspire E5-511P with bios Insydeh20. On UEFI it does boot USB-drive, even with passwords set. It boots on USB-drive with legacy set, but now my Wifi doesn't work. On older laptops no issues with UEFI, I just had to set boot order. And Wifi works just fine.
I bought a ThinkPad 540p that comes with preloaded Windows 8.1. As I want to dual boot the machine I tried to select the Legacy Boot option in the BIOS/Startup tab, but I can't do anything as the option UEFI/Legacy Book is greyed out and locked in "UEFI Only". Below it there is an option called: -CSM Support that is also greyed out and selected as [No]. (below these options there is a little note with an asterisk saying "Unselectable for Secure Boot").
How can I enable the UEFI/Legacy Boot option again in order to dual boot the computer? I want to be able to boot from USB or from the CD Drive.
I'm trying to install Ubuntu on an e6530. I changed a BIOS boot setting from Legacy to UEFI. Now the laptop doesn't even show me a BIOS screen at startup. The screen is backlit, so power is on, but shows nothing. The drive light flickers a few times, but no matter how long I wait, nothing appears.
I can't even switch it back to Legacy because I can't get into the BIOS. Hitting F12 after power on does nothing. Is there some way to get it back to Legacy mode? Or simply reset the BIOS to default settings?
I have a HP Pavilion dv6700t and I'm looking in the bios to set the the sata controller to legacy mode so I can secure erase my SSD. Trouble is there's nothing there to do it. Question is, does anyone know how to set the controller to legacy mode?
I received my Dell Inspiron 15R - 5520 laptop and am attempting to set it up to perform a UEFI boot to a Windows 7 (64 bit) installation. I am using bios version A11 which is the latest available.
If I use legacy, I am able to boot fine to the Installation DVD and install/use the system. If I use UEFI (non-secure boot), it will freeze during the boot process for a long period of time. I do not ever get to the GUI to attempt installation. I have tried clearing the disk partitions using diskpart -> clean to ensure it is not due to having GPT vs MBR and have also tried changing the SATA adapter to ATA vs AHCI.
Alternately, I am able to boot to, and install Windows 8 RTM in UEFI mode.
Before I get a lot of responses of "Don't use UEFI", the reason I purchased this laptop was for the purpose of dual booting between windows 8 and windows 7 for development purposes, and require the use of secureboot to properly test the software I am developing. If this laptop is not able to run Windows 7 in UEFI mode, I will need to return it and select an alternate vendor.
For the last 2 days I have been trying to install Windows 7 x64 in UEFI mode on my laptop but it seems entirely impossible. Whatever I do, the boot menu (F12) just won't show any UEFI devices AT ALL, just the normal DVD and/or USB options. Obviously when I try to boot from either normal DVD or USB, Windows 7 setup freezes at the "Starting Windows" screen, I'm pretty sure that's because it is not running the EFI bootloader of the setup.
For the record, I can't just install Windows 7 in Legacy/BIOS mode because it is then impossible to install the Synaptics Touchpad driver under Windows because the Touchpad device is not discovered for whatever reason.
Yesterday I flashed the firmware of my XPS L702X to version A19, which enabled UEFI boot mode. I decided to go ahead and try to install Windows 7 in UEFI mode on a GPT disk. Installation succeeded, booting failed however. Then I read a message on the web from someone who succesfully installed Windows 8 on the same machine in UEFI boot mode on a GPT disk. So I decided to try Windows 8 instead. Installation failed. Using the recovery menu from the Windows 8 installation media, I wanted to try and see how far installation had come and more or less accidentally selected in some "Advanced options" menu to reboot to my USB flash drive (where the Windows 8 files were on). Rebooted fine. Then I shutdown, using the regular option.
When I turned on my machine again, I found out that pressing either F2 or F12, for the firmware setup and the boot menu, respectively, didn't work anymore. The firmware recognised my input, as the text in the lower right of the Dell splash screen became lighter, but instead of entering setup or the boot menu went straight ahead to boot my existing and working Windows 7 installation on my first (MBR) hard drive instead.
So, in short, I am locked out of setup and the boot menu. I have already tried reflashing the firmware, but without any luck. What to do now?
I have been struggling with installing w8 on my Ideapad z510 laptop in UEFI mode, but neither I could succeed it nor I could I find something that might work. I will clearly explain the case.
Point 1: As I understood, to succeed w8 install in UEFI format, one needs to choose "UEFI First" mode from Boot Menu in BIOS. Then, the source of the boot needs to be specified to identify the rigid path to the documents to load so that new OS could be installed correctly.
Problem1: It is possible to chose UEFI First from boot mode, but it's not possible to choose the USB path for UEFI booting in this case, which doesn't allow you to succeed a UEFI boot to your computer. You can't reach the DVD or USB, where the installation files are, and start installation process.
Point2: Considering the first case, you need to choose Legacy Support mode to boot your computer and reach USB disk or DVD to install new OS on the computer.
Problem2: To succeed UEFI mode booting to the computer, you need to see 4 different partitions on your disk at point of disk selection, where you choose the disk you'll install your OS. However, when you select the Legacy Support mode from BIOS, the disk partition is limited to 2 in my case, which are:
Primary diskSystem reserved (350 MB)Hence, when I continue with the installation, the OS is installed on Legacy mode. After installation, when I go to BIOS to choose UEFI mode for boot mode, the laptop checks some connections from network and says
EFI network 0 for IPv4 failedEFI network 0 for IPv6 failed respectively.
PS: Please don't tell that "you can't install, because your computer doesn't support", because I received the computer from technical service and a version of W8 was installed on it in UEFI mode. However I deleted it to install W8 pro.
I unplug my laptop and after 15 mins it says "your battery power is low (7%) if you don't plug in your computer soon it will hibernate automatically". I know its fully charged and i press the button on the battery and all lights are on..what should i do?
My Vostro 1000 has recently been failing to charge the battery. There's no adapter warning, no battery warning, nothing. It'll indicate that it's charging normally, so I will leave it overnight to charge only to find it deader than a doornail the following day. I typically shut it down when I'm not using it, so it's charging with the power off anyway.
The battery is a nine cell Rayovac COM 10025 and the chargers are both Dell PA-90s. I know one of the chargers has a break in the communication line, but I can still get it to charge the battery if I hold the wire just right as I put the plug into the computer. The other charger, which is my main one, seems to work OK.
When this happens, the laptop will not charge the battery at all until I pop the battery out and back in. The battery is only three months old, so I shouldn't be having trouble with it. The last battery, which had to be replaced under warranty, was the same model and had lost 2/3 of its capacity in less than a year.
I'm looking to upgrade the RAM on my Vostro 1000. However, I've been reading conflicting information across the web (including some posts in this forum) which state that the maximum amount of RAM this system can take is 2GB ......
On my Dell Vostro 1000 which is equiped with a TSSTcorp DVD+-RW TS-L632H ATA DVD/CD writer, it appears I can't write to disk anymore. I can still read DVDs and CDs without errors. Just when I attempt to burn disks, the drive fails with unspecified errors. One thing I noticied is that when I recently used Roxio to burn an ISO image to a CD, the operation completed. But when I reinserted the disk nothing was found on it. It appeared to be blank when reading it from the Vostro laptop. So, I inserted the disk into another DVD/CD drive on another computer. The CD appeared blank but when I tried to write to it from the other computer the pre-write check reported that only 13MB of space was available. So something was on the disk but it ws not visible to either computer. Weird. I tried cleaning the optics but the write operation still failed. Should I consider the drive dead?
I have a question regarding my Dell Vostro 1000's battery.
To start off, I did the recharge and discharge method and after that, when I disconnected the AC-Power, it only shows the "Total Battery Charge 100%" but the primary, it doesn't say anything. Plus, when it was unplugged, it stays at 100%. Few minutes later, it will drop to 7% and the Battery LED will flash orange to tell me that the battery is low.
And my Battery health is good, but why is Windows 7 not detecting the battery charge properly??
