Lenovo G505 Will not boot in UEFI or Legacy Suppor...

Q: Lenovo G505 Will not boot in UEFI or Legacy Suppor...

My Lenovo G505 laptop running Windows 8.1 gave me error messages that say:"EFI Network 0 for IPV6 boot failed.""EFI Network 0 for IPV4 boot failed.""Default Boot Device Missing or Boot Failed. Inset Recovery Media and Hit any key. Then Select 'Boot manager' to choose a new Boot Device or to Boot Recovery Media"Then it goes to the boot option menu and gives me a list of the two boot options:"EFI Network 0 for IPV4""EFI Network 0 for IPV6"with no option to select the HDD despite BIOS being able to detect it.I changed the boot mode to Legacy Support from UEFI, and this time on the boot option menu I got a choice to boot from the HDD or the ODD. When I chose to boot from the HDD I got another message saying "Check cable connection!" PXE-MOF: Exiting Intel PXE ROM."I tried to boot Ubuntu from a flash drive and from a CD, but I still got the same result as when I tried booting from the HDD.I think the problem is that my Laptop won't boot in legacy support, but when I use UEFI I only have the option of booting from the network. I have no idea how I could fix this, so any suggestions are appreciated.

Preferred Solution: Lenovo G505 Will not boot in UEFI or Legacy Suppor...

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.)

hi MattQE,

Welcome to the Forums.

Just to verify, is the unit originally Windows 8 and this problem occured after you upgraded to Windows 8.1? Any changes that you made to the machine before the problem occured?

From the looks of it, this seems like a hardware failure but can you try the following:
1. Boot into the BIOS and set the following options (if applicable):

Security Tab:
Secure Boot = Disabled

Exit Tab:
OS Optimized Defaults = Other OS / Disabled

2. When done, press Fn+F10 to save and exti and observe.


Let me know how it goes.

Hi all,

Currently having a wake on lan issue with a certain computer.

The machine is setup correctly but the windows boot information is stored in a 100mb UEFI partition, and when the computer wakes on lan, it will not boot windows, just sit at a blank screen.

When it wakes on lan it is trying to boot from the legacy device (same blank screen happens if you choose to boot from it from bios)

ive tried updating the bios but no luck, all settings seem to be as they should be.

Is there some trick to get it to load the UEFI MBR, or is there a safe way other then reformatting the machine to move the MBR over to the legacy device itself?


Thanks for any help.

A:Boot UEFI from wake on lan, or convert UEFI MBR to legacy.

Back up your files, unplug all other HD's and peripherals,

Boot into BIOS setup to enable Legacy BIOS. Next check BIOS Boot order for an EFI Boot Disk: remove it, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed here.

At first installer screen Press Shift + F10 to open a Command Box, type:

DISKPART
LIST DISK
SEL DIS 0 (after confirming Windows 7 target HD #)
CLEAN
CONVERT MBR
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

Hi, My comany is purchasing HP EliteDesk 800 G2, some comes with HDD and some with SSD.We deploy Windows 7 x64 using SCCM using legacy boot. On a machine with HDD installed I can configure the boot options to use legacy boot, but when I replace the disk to a SSD drive the only boot option for this drive is UEFI.That causes the deployment to fail because the drive need to be partitioned as GPT.On the other hand, if I disable legacy boot, PXE boot to UEFI and partition the disk as GPT, after the image deployment the disk is unable to boot with 0xc000000d error (I imagine the cause is Windows 7 support becuase it does work on Windows 8.1). Bottom line, I can install Windows 7 on a HP EliteDesk 800 G2 only if legacy boot is enabled and I partition the disk as UEFI.Is there any way of forcing the SSD to boot as legacy and not UEFI?Is this issue caused by the workstation or is it enforced by the SSD? thanks.

I have disabled the secure boot option and enabled the Legacy boot option which allows me to boot from USB stick. However, UEFI takes precendence over Legacy boot and I don't want that. For a little school project that we are running we want to run the educational OS Sugar on Stick(on a USB stick) to run straight from the stick instead of kids pressing 3-4 different buttons to get to that.  In short, I want to change boot priority from UEFI first to Legacy.

If your PC or laptop supports UEFI and legacy mode then the following tips may help you. Legacy enabled:If the bios setting is legacy enabled then hard drives and USB devices will normally boot.  If you are using two independent hard drives that are not connected by boot manager then the UEFI boot hard drive will always boot first before the legacy hard drive unless the bios allows you to change the boot priority. Legacy disabled (UEFI mode):If the bios setting is legacy disabled then only UEFI devices will boot.  You may run into no hard drive selection menu, no boot option menu or Boot Device not Found followed by a message Hard Disk (3f0). USB flash drives boot considerations:If you wish to boot up a USB flash device using Windows 7 repair, Windows 8 repair, Windows 7 or Windows 8 installation media then be sure to create the flash drive formatted as FAT32.  You may notice a bootable flash drive showing twice in the boot menu, one marked UEFI and one not marked UEFI.  Both will boot up. The popular MS Windows 7 USB WIndows installation media creation tool will create a NTFS flash drive using a Windows 7/8 iso file in NTFS format which is not bootable in UEFI mode.

Hello, first post here...

First, some context: I have a Dell Inspiron 15R SE that came with Windows 8.

I've managed to get a working dual-boot system with Ubuntu 12.10. I can't remember exactly how I done that, but I remember that I had to disable secure boot. I think that the boot configuration those days was:
Secure boot: DisabledLoad legacy option rom: EnabledBoot list option: Legacy

This "configuration" worked perfectly for 6-7 months.

Then, one day (last week, can't remember the exact day), when I was using Windows 8 the computer crashed. I hard-rebooted and got this screen:

I've searched a lot, looking for solutions and after executed boot-repair from a Ubuntu LiveCD dozens of times I've decided to eliminate Ubuntu temporarily and focus to get a system with Windows 8 working nice.

Then I used my recovery DVDs to recover the system. Yup, Windows has booted. But when I restarted first time I got the same error. Then I, digging a solution, pressed F12 after a reboot and got here:

The highlighted option allows me to boot into Windows 8. So I went to boot options (F2) and changed the following configuration:
Load legacy option rom: DisabledBoot list option: UEFI

Now I can boot directly to Windows without need to press F12.

But my objective isn't complete. I want to erase all Ubuntu entries from the seconds image and restore the legacy boot from the first imagem (because they worked before).

Hi there, My Lenovo G505 is not booting anymore. I had wanted to scan my laptop with Kaspersky Rescue CD, and therefore, I wanted the laptop to boot from the CD. So, I searched for how to boot the laptop from CD, and I followed the solution provided in this thread by Solid_Cruver: https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Lenovo-Z500-BIOS-legacy-support/m-p/1124815/hig... As written in that post, I first booted to BIOS Setup, then under Exit, I changed the "OS Optimized Defaults" to "Other OS". I then hit F9 to load defaults. Then, under BIOS, I changed to Legacy boot and Legacy first... both options that are shown one below the other. After that I saved the BIOS setup and exited. After that when the laptop boots, it just keeps showing Lenovo on the screen, and under that the dotted circle keeps on spinning, and nothing else happens. After waiting for a while, I turned power off by pressing the power off button for a while. Then, I pressed the Nova button, but no display comes up, but the light for power remains on. Again, nothing happened there too. Just a black screen, even no blinking cursor, or any kind of display. After waiting a while, I pressed the power button, and laptop powered off. How do I get to the Nova screen, or get the computer to boot? Or, how to just set the BIOS setup again to what it was before? This isn't my laptop, but of my friend, and I don't want it to go bad :/.

OK, I tried again after power off on the Lenovo screen. I then pressed the Nova screen, and this time, the display was there (phew), and I got the options for the Nova screen.

It again shows the screen with Lenovo written and the dotted circle keeps spinning. What else do I have to do to get the laptop to boot normally from the OS? Under the BIOS settings, I noted that Secure Boot was Enabled, but the Secure Boot Status was Disabled. The laptop isnt booting because of this setting? How do I get the Secure Boot Status to Enabled, and how do I get the computer to boot normally from the OS on the HDD?

Used rufus to burn image to usb, made sure that is gpt as well. For fun, tried the system restore function, but fails right away. I just deleted the windows partition (not the entire drive).

A:how to boot usb in uefi mode (not legacy) for inspiron 3531

When you reinstall there are some critical partitions.  You cannot leave any of those of the drive and reinstall Windows 10.  Data partitions should be OK.
To boot a USB drive as UEFI, assuming your system has that capability, you have to format the USB drive as FAT 32.  It must use an x64 bit version of Win 10.
When you boot you should be able to see a Boot Device Menu.  Look for something that shows as UEFI and boot to that.  If you don't see a UEFI option, the Bios may be set incorrectly or the USB drive is not configured correctly.

Just bought a Dell Optiplex 7010 Mini-Tower with Win 8 Pro 64-bit, 8 GB RAM, 500 GB hard drive and an Intel i5 3470 processor. Right now, it has Dell BIOS version A16.

It is normally in UEFI ON and Secure Boot ON, so that F12 on bootup (one-time boot options) does NOT normally show the CD-DVD as a boot option. OK - no problem.

However, if I reboot with F12 and select both UEFI OFF (meaning Legacy ON) and Secure Boot OFF and reboot, then F12 DOES show me the CD-DVD as a boot option, but if I actually try to boot up from a bootable CD, I get an error message.

I have practiced with two bootable CDs - a Knoppix and an Aomei Backupper, both made on earlier machines. Both these CDs work as boot-up CDs in my old XP machine, and the Aomei Backupper CD also worked in someone else's Win 7 Pro 64-bit machine.

What's wrong?

Again, please let me repeat that I am trying to boot from the CD-DVD AFTER I have turned OFF UEFI, turned ON Legacy and turned OFF Secure Boot.

Thanks.

My W10 64bit Dell desktop installed KB3194798 on 10/12/2016 using Windows Update (WU) so now it is 1607 1493.321.
Today I tried WU to update my Lenovo G505 W10 laptop and I think it might have been KB3194798 that has killed my laptop, but I cannot even get the laptop to go past the black screen to the Lenovo display when trying to boot.
Here's the history...
Today I pushed the power button to turn it on and found that my wife had left it on and over the many hours it had gone into (I assume) a powersaving mode that made me think it needed to boot.
The screen showed that WU was up and some KB was at 94%. I left it alone and a few minutes later it told me the install was ready to go. So I clicked to let it WU do the install. The install failed saying some files were missing but it let me click on "retry".
I think it failed a 2nd time. The 3rd time it appeared to be installing OK, and I went to work for a few hours. On my return it showed that the laptop required a restart to complete the WU installs - that's pretty normal after letting WU do an install of a "cumulative", I think. So I clicked to restart and walked away. When I returned hours later, the laptop was still displaying the Lenovo boot-time logo and the spinner was spinning. I powered down the laptop by holding down the power button. Now the laptop will not even display the Lenovo boot-time logo. The little power LED is lit.

So I downloaded the Linux image and I was so excited to install it. So I needed to disable secure boot from the UEFI Firmware Settings, but for a whole month I tried every single method I could find online to get into UEFI (holding/tapping esc/f1-f12, etc.) I restored my laptop to factory settings but I still can't get it to enter UEFI settings. Its been a year now and I still can't get it enter no matter what I try.

I am not a happy camper with Windows 8.
I am confused with the Legacy and the UEFI boot methods. The reason I am confused I think, is because I read to darn much on the Internet. One bit of confusion is with respect to changing from UEFI to Legacy. It would appear from some comments that if I do that, Windows 8 won't boot anymore. I would have to change back to UEFI for indows 8 to boot. I also read that changing back to UEFI could be a major problem when trying to access the BIOS. No, I am confused. My ultimate goal is to set my laptop up to dual boot Windows 8 and Ubuntu. Like I have been doing for the last multiple years with XP and Windows 7.
Helpful comments would certainly be appreciated.

A:UEFI/Legacy

I don't quite understand what UEFI is, it is firmware, or is it Microsoft's new Boot GUI? I've set my systems to boot Legacy mode, and since I did that, I have no trouble getting into Safe Mode.

Does UEFI access your BIOS as well? That's what I'm worried about. The idea of not being able to access the BIOS from outside Windows 8 makes me itch. I think the Legacy Menu may allow that though - You can set it to Legacy, and if you can't access the Bios, then you can switch it back. I forget the command lines to set it, but they are in a tutorial here. It's BCDedit.

Hello,

I have just finished making myself a decent gaming rig and im on the last step at the moment; which is installing Windows 7. I have noticed that when trying to install Windows on my pc there's two option: one is Legacy and the other is UEFI, and since I'm not really and expert when it comes to such things, I decided to postpone the installation process until I figure this out. So, which of these should I choose as an installation method? I'd really appreciate it if someone could help me with that. Thank you!

A:UEFI or Legacy?

UEFI has some advantages over BIOS,such as:

Faster booting
Support of 128 logical partitions
Support for disks which have a size of over 2.2 TB
Support for Legacy BIOS

Since your desire is gaming,install with UEFI. There's no reason to go with BIOS unless you have old hardware.

Hi,I bought a new Ideapad 320, which came with DOS based OS. I was trying to install windows 10 on that. I created a bootable USB through Rufus. But I was not able to boot from that, however I was able to boot another dell laptop with the USB. Then I created a bootable DVD and tried to boot, but again the ODD was not listed on the boot manager (this was because by default the Boot Mode was UEFI). So I changed that to Legacy and I was able to boot through DVD. I installed Windows 10 but I had problem with USB and Camera. USB was working in mass staorage mode, but when I connected wireless keyboard/mouse's receiver, USB Headset; none of them got identified. In device manager I see "Port Reset Failed" for USB. I tried updating the USB drivers but nothing worked. I think I should install windows in UEFI mode. But in UEFI mode I am not able to boot from USB. I tried creating USB for UEFI through Rufus also I tried to create that manually using Diskpart and manually copying the ISO content, but unfortunately nothing is working. I do not know whats the issue. Can someone guide me how to created bootable USB to be used to install Windows 10 PRO x64 in UEFI mode.

Hello, first of all thanks for taking time helping me with my issue.

That`s the case:

I wanted to recover an Image-Backup done with a Backup Software, but the Boot-CD does not Boot on my PC. I have an Windows 10 64-Bit System.

While trying i found out it does indeed boot when i change the Bios from UEFI to Legacy.

If i recover the Image in Legacy-Mode and after that i change it again to UEFI - will Windows boot up or will there be Problems?

Is there any way to make the Boot-CD work also on UEFI?

Thanks in advance.

My XPS 8700 originally came with Windows 7 Pro, 64.  I since upgraded to Windows 10 Pro, 64.  I only now noticed that BIOS is setup for Legacy.  If I attempt to setup for UEFI MY drive is not recognized.  A check shows that the drive is setup for MBR.  I thought all XPS 8700's came setup for UEFI.  Am I stuck with Legacy or can the new drive be setup for UEFI???

A:XPS 8700 Legacy or UEFI?

I'm not 100% sure but I think UEFI requires drives to be partitioned GPT.
Remember, backup your Data.

And don't forget to backup your data. The conversion will format the drive.

Hi, I just purchased the HP x360 Spectre, which came with Win 10 Home and UEFI/SecureBoot turned on. The boot disk is GPT. Also, there are 4 partitions on the drive out of the box, as listed in the : EFI SystemRecovery PartitionRecovery ( D: )Windows ( C: ) This is my first Windows above 7, and the first that is not Legacy BIOS and MBR boot disk, so I'm a little lost with all this. I need to backup the drive before making changes to the new laptop using my Macrium Reflect Win7-based PE USB pen drive, but when I disable SecureBoot and enable Legacy Boot and move USB key to the top of the boot list, it boots Reflect under PE OK, but no drives are shown in Reflect to back up. I'm not sure at this point if this is because Version 5 of Reflect doesn't support UEFI (although I'm not sure that's a factor as I've booted), or some other factor resulting from UEFI and GPT. I know Reflect V5 can backup GPT drives, as I do it now, but have only imaged MBR drives. There are newer version of Win PE; Ver 4 based upon Win 8, and Ver 5 based upon Win 8.1, which might solve my problems. I'm trying that next. If anyone has any insight, it would be much appreciated. Also, are UEFI and BIOS connected in some way to MBR and GPT, so that one requires the other, or can you mix and match. For example, could I have machine using UEFI and an MBR boot drive, or vice versa? I'm just not sure what, at this point, is making my drives not appear in Reflect. Also, is there a way to conver...

Hello,

Right before I performed a clean install of Windows 8.1 x64 on my Inspiron 3520, I switched to the Legacy BIOS *facepalm*.

When I enter the legacy BIOS and enabled "secure boot", I performed a restart that gave the following message "internal hard disk drive not found, to resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 enter setup menu, F5 enter PSA". Of course, when I go back into the BIOS and disable secure boot, it reverts back to legacy and boots up Windows 8 just fine. What I'd like to know is, how can I revert back to UEFI so I can change the boot-up option and perform a clean install under UEFI.

Any help would be greatly appreciated! I've found a couple articles but I just want to make sure I'm headed in the right direction and if maybe there is a safer and easier way to get this done...
