Fedora Installation :: F11 Grub Will Not Recognize Password
Sep 27, 2009
I have just installed Fedora 11 64bit on a new hard disk, using Intel 975BX2 motherbord, 3Gbyte RAM, 320Gbyte hard disk etc., USB mouse and keyboard. The installation went fine, but when I enter the password for the boot (I assume GRUB was installed) it fails to recognise the password. Do this three times and the boot segment ??? fails to initialise.
I recall a linux magazine i buy indicating that you have to copy and paste the password manually after installation, but i cannot recall the article date. Is this a problem - the password protection for the GRUB boot loader does not work at installation time when using the graphical interface ?. I did not use any odd characters - basic letters and numbers.

First time this has happened. I installed Fedora first (XP already installed) and then installed Ubuntu 9.10 64. Fedora doesn't show up on boot up menu. I've tried update-grub.
Before I would have just edited menu.lst, but now?? I dunno.
edit; Here's fdisk with Fedora on sda6

I recently installed Ubuntu 11.4 and I want dual-boot machine. Before Ubuntu on machine was installed only windows7. Since I install Ubuntu I do not see Grub(or any other) boot loader. When I start computer it automatically boot Ubuntu without prompting choose OS menu.
How can I set grub2 to ask me this question?
Here is my partition configuration
Code:
Boot Info Script 0.60 from 17 May 2011
============================= Boot Info Summary: ===============================
=> Windows is installed in the MBR of /dev/sda.

So I am experimenting with other linux distros.....I just installed a small partition with OpenGEU, the one still based on Ubuntu.....now it wont recognize Mint. Ubuntu Studio is next on my list, but before I invest any more work I want to make sure I can add more partitions to grub, not just the most recent linux partition...
I think that future distros of linux should have a fix for this....if you install linux it should detect every other operating system on the disk, not just windows plus the most recent linux install.
install /boot separate? I always create a / and /home partition but never separate boot. Does that make life easier?

i can't boot up my win XP after installing Ubuntu 10.10.
I decided to replace my Vista partition with Ubuntu 10.10 so i redo my partitions and split the current Vista partition to a swap and root partition and install Ubuntu 10.10
Everything went well and i got Ubuntu up and running. However, i realize that GRUB 2 didn't recognize my existing windows partition. I double-check on grub.cfg and see that the default os_prober didn't recognize my XP partition either.
After search on the internet for a while, i found many similar issue where most are fix when manually adding the entry yourself so i decided to add an entry 11_XP under /ect/grub.d/ for windows XP and confirm that the new entry are added to the update grub.cfg file before restarting
Code:
### BEGIN /etc/grub.d/11_XP ###
menuentry "Windows XP" {
set root=(hd0,5)
insmod chain
drivemap -s (hd0)
[Code].....

I migrated an old SuseLinux 10 box to Debian (Lenny) a couple months ago, and apparently no one noticed you can't change your password. Root can do it because passwd doesn't ask root for a password, but no one else can (although they can log in, passwd doesn't recognize their login password when they attempt to set a new password and it asks).I changed authentication to use blowfish when I setup the server (because the SuseLinux 10 system used it) and apparently the passwd command doesn't work with that. Apparently I need to update another configuration file or possibly get a different program to update the passwd file if I use blowfish. Any ideas?
The weird thing is that it can generate a blowfish hash to set a new password, but apparently can't generate one to authenticate the user.something changed recently and it is no longer generating a blowfish hash when setting a new password. It is generating a hash with only 13 characters. And I can clearly see that many users have changed their passwords.

I had Windows 7 ultimate installed on my netbook and installed Ubuntu 10.10 using the 'Install alongside other OS's' option which put windows onto another partition and created one for ubuntu.
Anyway I've tried reinstalling the grub but I never get a grub boot menu when I boot it up and the grub won't recognize the windows install

I recently have installed Ubuntu 10.10 Maverick Netbook Edition in my personal netbook. The thing is that I had installed Windows 7 in the hard disk drive so I decided to install Ubuntu alongside with it. After the process of installation everything was cool but I hadn't the Grub working. I then pressed the Shift button during the booting process so I got the Grub menu but it didn't show the Windows 7 partition. The Windows installation was not erased because its file system is present in Nautilus. I have tried reinstalling the Grub a thousand times but nothing changes. I have attached the results of the boot info script so you can have some info about my booting configuration.

I have dual boot (winxp) which has been working for over a year now.But for some reason recently, grub wont recognise the keyboards arrow keys. ie cant change menu selection. in fact it wont recognise keyboard at all it seems. Pressing enter wont work either. I have to wait for the timeout.
The arrows work before hand (like in bios settings) and after once ubuntu has booted. Just not in the grub menu
Its something to with the USB wireless keyboard. If i replace it for standard PS2 kybd it works.

I am new to Fedora. I know my top probably already been posted somewhere but I just could not find it. I just installed Fedora 11. But my root password does not work (I guess was my fault to type wrong in the first place or some type of short term memory lost). I looked at the root password recovery procedure which involves select single user at GRUB page when booting. But for some reasons, Fedora 11 does not boot into GRUB. I tried Alt+CTRL+F1, F1 or Shift, none of those gives me Grub screen.

I've just installed Linix 7.0 which I purchased several years back but never got around to installing it. I installed it on an older Compauge notebook . At the requested time I entered the user name and password in the setup program. But now when I try to log in , it does reconize any of the data I entered. Is there a way to reset it. I can't even get into the computer to delete the installation and re-install.

In getting my Fedora 15 installation up and running (which it mostly is, now, thanks to help from LQ!) I am at the point of installing thunderbird so that I can send/receive email. It seems to install fine, but when setting up the account it says that my username/password is not recognized. I know that I am typing them in right, and if I go directly to gmail with firefox rather than through thunderbird they work OK. Any thoughts? (I am also posting to the thunderbird forum at mozilla.)

I'm trying to do is protect the computer against housemates. The standard procedure I do with Lenny:
1. Password protect BIOS.
2. In BIOS, always boot from hard drive. Disable booting from any other device such as USB or CD-ROM.
3. Password protect Grub (v1) using the "password --md5 $1$9MuaA/$5TDLgvmcEiCWNr5W9VaMK1" syntax in my menu.lst file.
With the above precautions in place, [I think] the only way to gain root access to the system is to take the case lid off and proceed to do stuff physically (like set jumpers and/or take out the hard drive). Am I correct? My reasoning for this is, the computer boots -> must boot from HD -> must load Grub -> must go to default menu item since others are protected, and cannot command prompt in Grub without password.
Anyhow, In Squeeze, I was a bit disappointed to find out, after doing a bit of Google-research, that Grub v2 (which is standard on Squeeze now) does not easily support password protecting the Grub menu. Am I correct? Will this issue perhaps be addressed in the Squeeze final release? Is this feature dumb anyways because the Grub password is of no use (i.e. my paragraph above is complete horseradish)?
Another thing I would like to do is change the console font and size back to something more "normal" or "classic", not some crazy tiny font that's only found in totally bleeding edge Linux distrubutions <gasp!>. I found that the Squeeze console font (e.g. when I type Ctrl+Alt+F1) is wicked tiny. I wanna change it to "normal". Grub v2 password and console font config?

I had the same problem with normal ubuntu, wubi or even after instaling it in a virtual pc
I've got a wireless router with a WEP security, when I choose my connection and put in the key it just tries for some time and then ask me again for the WEP key. And it goes like this on and on and on, I've tried to connect at some firends gome with the same kind of connection and it doesn't work either.
I think that in an older version I did connect to an unprotected connection but I cannot take out the protection because it is my roomsmate wifi.

I am running Ubuntu 11.04 i386 and I installed the unity desktop by using sudo apt-get install ubuntu-desktop. However when I try to open the synaptic package manager it won't recognize my password. It just keeps asking me for the administrator password. I can open update manager which also needs the admin password. This is a fresh install all I have done is installed the ubuntu desktop. I am currently trying to install KDE desktop to see if it works on there. I also have had this problem on my laptop which runs 11.04 x64 desktop edition. Does anyone else have this problem or is it just me? and is there a fix? also what is the terminal command to launch the packet manager? edit. It started working on my laptop a week or so ago after I did updates. So I'm not sure if the server version of unity or the packet manager is just behind? I have run the update manager on my server and it says its uptodate.

There are 3 IDE drives in this box.
hda has Debian Lenny installed (with swap) and is to remain.
hdb1 has a linux distro on it.
hdb2 is a data partition and is to remain.
No other partitions on hdb.
HDD is data only (not really relevant but mentioned for completeness)
The system boots via Grub from MBR on hda.
I'm trying to install F10-i686-KDE-LiveCD on hdb1 but F10 won't allow it without modifying the partition tables which will, of course, wipe my data on hdb2. hdb seems to be a happy disk; e2fsck shows it clean and both partitions open properly in Konqueror within the LliveCD.

I am having a problem installing Fedora from a CD.When I put the installation CD into the drive and restart the computer, the computer does not recognize the CD and boots automatically into my old version (version 8) of Fedora.I have already made sure that the CD drive comes before the HDD drive in my BIOS settings, and I have already tried using different CDs.

I've just did a fresh install of Xubuntu 9.10 x86 in a 4 gig pendrive.Just one ext4 partition for / and /home and a swap partition. Only one user created during installation.Everything's fine so far except for two things:-If I launch synaptic from the start menu, it asks for my password which I type in or even copy-paste to be sure.Strangely it always comes back saying incorrect password. If I open a terminal and call "sudo synaptic" and type in my password when prompted, the application shows up fine. Again if I do the same via the Run dialog (alt+F2), that is "sudo synaptic", nothing comes up. If I just type "synaptic", a pop up says that as a user I won't be able to install anything and blah-blah, and the application displays properly

I have have just installed 10.10 on my Acer Aspire laptop. I connected to the Internet during installation and therefore should be right up to date. Grub2 does not show Windows 7 as a boot option. Did a bit of searching and ran sudo update-grub2 but no success. I am a newbie as far as Ubuntu is concerned. I installed 9.04 on my netbook and that worked fine. I have the added problem in having to get into Windows very shortly and I haven't a clue how to do it if grub remains broken. Windows partition still there I have not deleted it.

I'm trying to install Fedora 10 from a USB memory stick on which i've installed Fedora-10-x86_64-DVD.iso and, early in the process of configuring the installation, i get messages about both my IDE hard drives having unrecognizable partition tables:
"The partition table on device sda (... my disk data ...) was unreadable. To create new partitions it must be initialized, causing the loss of ALL DATA on this drive."
Same for sdb.
My PC currently runs Fedora Core 4 (yes i know i should have gotten around to upgrading my OS earlier) and yes it recognizes both hard drives just fine.
The answers I've found on the web suggest to backup my drives and repartition. I'm not too hot on that "solution".
explain why a F4 partition table is not recognized by F10?
BTW, I've recently upgraded my motherboard, processor, DVD drive, regrouped both my IDE drives on the same bus, ... I consider it a miracle F4 still runs on this PC (although F4 does not support the motherboard's graphics card, so no X11).

I have this laptop that I just reformatted in hopes of doing a dual boot between XP and FC4. It is an Acer Aspire 5315-2153 (the Wal-Mart special). I reformatted the drive; the Windows partition is in NTFS and then I have a 10GB partition in FAT32 for Linux. When I try to install FC4, the disk boots into the installer, then it tells me that it does not recognize any hard drives (the disk in this laptop is a Hitachi HTS541680J9SA00). It asks me if I want to load any drivers, and I tried a few and still no success. Any way, after it goes through that, it tries to start anaconda and after that launches it goes to a black screen and nothing happens. So, did I do anything wrong in the Windows install that won't allow the disk to be found? The XP disk only allows a format in NTFS, otherwise I would have done FAT32 on the whole drive. Second, is the anaconda problem something related to the HDD issue, or does anyone think that it may be a separate issue?

Being able to reset the root password by booting into single usermode by editing grub. This is a MAJOR flaw. I know it makes no real difference against internet bourne attacks, but even so I must say I found it shocking. The only way I've found to stop this is to encrypt the entire HDD, so noone could get into single user mode without first knowing the encryption key/password.
