Ubuntu / Apple :: Disks Disappear Suddenly While MacBookPro Installation
Mar 2, 2011
Im trying to install Ubuntu on my Intel MacBook Pro 13". When booting from the livecd, Im experiencing strange issues. Sometimes the partiontable and disks/partitions are not readable straight away, sometimes you can read them once (when opening gparted or the install-routine), but then they disappear after it. Sometimes they remain quite a while and "survive" all parted and other tools, and then produce I/O errors during install (after successfull partitioning).
I want to know... are these issues well known or am I the only one with such errors? Im not doing anything wrong, AFAIK. The devices just disappear sooner or later until only loop0 (cd-rom) remains.

I installed 32-bit 10.04, and only see 2GB of the 4GB available:
Code:
$ free -m
total used free shared buffers cached
Mem: 2193 1223 969 0 57 817
-/+ buffers/cache: 348 1844
Swap: 4092 25 4066
I was expecting to see 3GB of memory (since I installed 32-bit Ubuntu), which is what I was used to on other systems, but 2GB seems odd. Is there a way to improve things?

Last night I installed ubuntu 10.10 unto a macbook pro 5,5 following the instruction from the MactelSupportTeamAppleIntelInstallation however I made a mistake during the installation process. I forgot to go into advance settings and choose to install the bootloader on /dev/sda3. I'm not exactly sure why this step was needed since everything was working fine anyways, but I was wondering how can I remove the bootloader from /dev/sda and install it on /dev/sda3 without breaking anything.

I have a MacbookPro 5,1 with 2GBRAM, which successfully dual-boots with Ubuntu 9.04 since a year. I wish to urgently install ubuntustudio, and also wish to have one or perhaps two more partitions, where I may install the latest Ubuntu as well as another Linux distro.
Typically, think of a multi-boot scenario:
Mac OSX 10.5.x
Ubuntu 9.04 <<--working production install, not to be messed.
UbuntuStudio 10.4
Ubuntu 10.10 [just a few days left!]
Fedora or Knoppix or Debian.
if possible, i'd also like to keep one partition free and unallocated, or reformat a partition, if i ever need to install windows. any thing i'd need to watch out for in this? I've got no extra or free partitions, only free space on the mac partition, that i'd like to carve out and allocate to partitions. Also, before i begin, is there a way I can clone my entire mac+linux hard-disk so in the event of a failure i can get *everything* back, mac as well as ubuntu? I bought a hd of an identical size, but use it with Time Machine. I'd rather use it to clone the entire hd.

I wanted to try to Natty 64 on my wife's Macbook Pro 2.1 (Core 2 Duo + ATI X1600) and I got a FAIL.
Indeed the LiveCD doesn't start at all, I don't even get the Try/Install GUI, just a sort of choice:
Code:
1.
2.
Select CD-ROM Boot Type : And a blicking cursor, I have no keyboard control at all, and I can't get something other than switching off the Mac.

i was experiencing slow start ups since i installed ubuntu 11.04. it took about 20-30sec for the apple logo to come up (or rEFIt). today apple released EFI firmware updates which doesn't seem to install. reason is that the partition scheme is not compatible. EFI Firmware updates only install from GUID partition schemes.
DiskUtility tells me i have MBR. So it seems like Ubuntu changed the Partition Scheme.
Can any body confirm that? how can i make sure ubuntu installs into existing GUID? i will re-partition later today and give you an update if the EFI firmware update installs and boot time is faster.

I recently installed ubuntu 10.10 x86_64 on my Macbook Pro 3,1 which has an nVidia 8600M GT video card. The native screen resolution for my system is 1440x900.Ubuntu is installed booting through Grub2 straight from my EFI firmware through rEFIt. I have to disable quiet boot and splash screen but I can boot into a shell.From there I obviously tried startX, but much to my chagrin it did not start. I screwed around with drivers and the like for a bit and ended up reinstalling completely to try and rule things out one by one.
I started by blacklisting nouveau, which didn't load nouveau but also didn't work. I then tried installing the newest nVidia drivers, which also didn't work.Everything I tried gave me the same error, "no screens found".I below is the most resent Xorg.0.log dump with the attempt at running with the nVidia driver.
Code:
[ 3242.793]
X.Org X Server 1.9.0
Release Date: 2010-08-20
[ 3242.829] X Protocol Version 11, Revision 0
[code]....
I am a computer science student so I am not completely inept, however I just cannot seem to figure out whats wrong with this thing.

I am about to install Ubuntu onto my MacBook Pro (5,2).However the hardware configuration is a little unusual, and may cause complications.I have removed the optical drive, and replaced it with a SSD, onto which I wish to install Ubuntu.Since this will be the second internal HD, whatever bootloader I'm using will need to be able to see this second disk, and perhaps the MBP hardware may have trouble with this (I don't know)?My questions are the following:
1) What bootloader should I use? (I'm not sure what exactly are the distinctions between rEFIt, grub2, grub2-efi, etc.)
2) Which partition[s] should I install this bootloader on? I am confused about whether I will need to install grub2 (or grub2-efi?) on the MBR of 'sda' (the HDD), or perhaps on the 'EFI partition' on that disk (originally created by OSX?), or perhaps somewhere else, or even at multiple locations.
3) How do I perform this installation? A link to the right (up-to-date) guide would be appreciated. (I've been browsing through perhaps rather too many help pages and forums, all written at different points in time over the last few years, when the technologies (GRUB2, distros, etc) were at different levels of advancement. And in that time, people have made progress in getting various things working on MBPs, their methods will have changed, and so will their advice/recommendations.) One thing in particular that I'll need to know is what to do when running the Ubuntu installer, to direct it to put the bootloader in the right place (or maybe we won't want the installing of the bootloader[s] to be handled by the Ubuntu installer). Also, it's still unclear to me what things like 'GPT-sync' (or 'bless') do, and what role they might have to play in this.
4) How do I accomplish this without having an internal optical drive? In the past I've been unable to boot MBPs from a Linux USB drive, and I understand that there are particular MBP issues with this. FWIW, the main HDD has already been partitioned into OSX and Windows (which I don't care about being able to use, actually, so if a proposed method makes Windows unusable it's of no consequence really). As such, perhaps some installation (eg of bootloaders) can be performed from within OSX? Alternatively, I do have USB sticks and a USB external optical drive that I can use. I also have access to another computer that's running Debian, so I thus have access to any Ubuntu/GNU software tools that may be needed. Finally, I can even put the optical drive back into the MBP temporarily if necessary in order to accomplish this installation.

I have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)
Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?

I'm trying to install Debian 6.0.1a on a MacBookPro5,5 (intel core 2 duo - EFI firmware). I have rEFIt 0.14 and a live cd of Debian (on a usb stick). I'm installing Debian on a usb stick. The installation process goes along smoothly, but then, it's impossible to boot up the freshly installed system (I get a black screen with a blinking cursor). I read that this is a common problem but all the solutions I have found have not worked for me.
The underlying idea is that since Macs have EFI firmware instead of a BIOS, the partition tables of devices are different (GPT for EFI versus MBR for BIOS), and grub is incompatible with GPT (I know there is an EFI version of grub but it is said to not work well). So the devices must have both a GPT partition table and a MBR one. These have to be "synced".
The tools available for this are:
- rEFIt can sync the partitions, but I haven't managed to have it sync them on any other device than the main hardrive. If I sync the main hardrive, then even the live cd (which is on a usb stick) won't boot (black screen with "GRUB _").
- Debian has a tool called gptsync, which returns a message saying "no data partition in gpt table, nothing to sync".
- Mac OS X has a tool called gptsync which returns a message saying "unknown partition type detected - I'm not touching this disc".
The reason there is no data partition is that gptsync sees my main partition as "EFI system". If I could change that, maybe I could sync the partition tables. Can that be done? Also, something I don't understand is: the live cd boots fine without grub. So why do I need grub? Couldn't the system boot up without it like the live cd does?

Is it possible to create a boot CD to boot external volumes on an Apple iMac 7.1 (which has an older firmware version and cannot boot external disks, unlike the MacBook Pro 5.1 which can do it, at least with grub-legacy which is all I'll ever use until EFI boot becomes available). There is some promising stuff on www.pendrivelinux.com, and I'll try it, but the instructions are for Windows, and I am not sure how to translate the menu.lst entry to linux (I suppose it would have to be entered in the "automagic" section). Of course I don't want to create a bootable flash drive but to use my external volumes that already boot on the MacBook Pro without altering them, except for installing the ATI video driver (but I have no problem booting in low graphics mode).
Until karmic there was a trick to make the iMac mistake the external volume for an internal one (the root partition had to have the same UUID as the internal root partition), but this does not seem to work for lucid. Anyway this UUID trick is dirty and causes problems when you want to edit the internal partition (which is the point of the external boot - you get a customized maintenance environment that boots much faster than the CD).

I upgraded to 10.4 netbook remix on my Asus N10 with an Nvidia card. I normally don't use the card and to get rid of troubles don't install the driver. After update something went wrong with the driver and I can't fix it. When the PC finished his boot het ask to give the password for the default key ring as usual but the window disapears before i can change anything. So this one is no too bad as my password is very easy and I can do the job with switching windows and keying very fast the pwd.
But try to read your evolution mail in these circumstances. I tried to start in low graphics mode but didn't help. Finaly I installed a fresh version on a separate partition and asked to copy my Evolution and Firefox documents. He didn't, dn't know why and tryed twice. So far my fresh installation works well but I lost my mails and shortcuts. So.... I think the easiest would be to work from the new installation as on the old one even the terminal window disapears.

My computer now fails to get a connection or even recognize that there is a connection it could well connect too. I have tried everyting every one has said before... i went in to terminal to install fakeroot,patch,bcmwl kernals and dkms ect ect.. I know that i have a broadcom bcm 43xx wireless card and that it worked this morning.. and that f2 and fn should turn it on. but nothing seems to work..

Computer was working alright, no one was really using it anymore so I decided to reformat it and install Ubuntu. The whole install process went through but when I restarted the computer it was all glitchy and anything that came on screen would disappear after an instant and then come back. Makes reading anything extremely hard. Realized I only have 256 MB of RAM which is probably a big problem which I understand but I need a solution to fix this. Any older versions of ubuntu or other linux distributions that I should try?

I have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?
I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);
dd if=/dev/zero of=bigfile.txt bs=1024 count=1000000 when this comment was run in SAS disk server, I took this output(10.000 rpm)
(a new server,2 CPU 8 core and 8 gb ram)
1000000+0 records in
1000000+0 records out
1024000000 bytes (1.0 GB) copied, 12.9662 s, 79.0 MB/s (I have not used this server yet) (hw raid1)

I have a working system with triple boot (Macos, Debian and Windows Xp).I have total 4 partitions, EFI, Macos, Linux Ext3 and Windows Ntfs. At this point I want to split my Windows partition and turn into the new user "Home" partition. I vaguely remember that there might have been some limitations with number of partitions regarding multiple boot schemes. Does anyone have an idea if there would be any problem if I go ahead and split my Windows partition and end up with 5 total partitions on this laptop?

1. Install kernel: see #2 (I make it with kernel file in /var/cache/apt/archive)
After installation of kernel, there may be some problems:
2. Win7 disappear in the grub: see the content below "Not see Windows 7: ", #6
3. Cannot connect to the network: see #8.
Quote: While trying to remove old kernels, I delete all of them by accident!!! There're now only two "Memory test" and a "win7" in the grub. Since there's lots of data on the disk, and I have no idea how to keep them safe if reinstalling the system, so I really hope not to do that.
Then I enter Ubuntu 10.10 cd, and sudo apt-get install a kernel (three 2.6.35 or so, of which two with "generic" and not, and one with "image"), everything seems OK. And I guess what I did really changed the system, since the source_list file in the /etc/apt/ did be changed. But the grub still has only 3 options. What else should I do to add the newly installed kernel to the grub? Or What should I do while I delete all kernels by accident?

I'm running F14 on an Intel i5 processor with a NVidia GT340 graphics card. Installation works great. Compiz Fusion runs too. At this point, the panels are a little unpredictable, in the sense that some items on the panels disappear and appear as they please; changes only come during startup. The userswitcher is usually absent (but not always). The show desktop icon is sometimes absent, and on a very rare occasion, the desktop switcher is invisible. For all of these items, space is reserved in the panel, and when manually added to the panels, that space is left blank; I can not move anything into that space. It remains reserved for the item that isn't shown.
Then I install conky. First installation works fine, shows all things that are called upon in the .conkyrc file nicely. It works fine until I click anything - even on blank space - on the desktop. Conky then disappears. The process continues to run, but it's no longer displayed. Upon reboot, all of my panels disappear, and I have no idea how to get them back. When I uninstall conky everything works again as before (the userswitcher being the least predictable item on my panels). When I reinstall conky, and add it to my startup items, it shows for a couple of seconds after log-in after which it disappears. I assume - but don't know how to check as I have no panels left so how can I run the system monitor - that the process keeps running, but it isn't displayed.

I turned on the computer this morning as usual, went into firefox, and some of the pages in the tabs look a bit strange, but i reckon they're just loading slow.Then I went into one of my sites that has images of some other sites that I designed. The images all seem to be there, so on. So I click through to one of the sites and... no images. Odd. Tried clicking where the image should be "View image" and it says firefox can't find it. Checked in ftp, the images are there and viewable.
Installed chrome and the site is perfect. Images showing up and everything.Still the same after a reboot.It makes cpanel really hard to use. Lots of sites including Facebook are just rubbish to look at (not just mine), seems the stylesheets may not be loading either in some cases. However, Ubuntu Forums is normal. In fact the whole thing is apparently completely randomAll is fine in Chrome.Is this a buggy version of firefox installed in the the latest update?

The HDD is brand new and hasn't been formated, partitioned, or previously had any other OS on it. The HDD is recognized in the BIOS.A list of possible drivers are listed in which don't match, except for two, but they don't lead to anywhere beneficial in order to complete the installation process.At this point, I have no idea how I must proceed.

Reformatting two drives before re-installation. I'm new to Linux generally. Can someone give me instructions on formatting the hard drives? I have installed ubuntu on a machine that had been running Windows for a while. Since Windows worked the boot drive for years, I decided to switch the positions of the two drives; putting the old data drive into the boot position.
Apparently, ubunta was too smart for me. I guess it discovered the Windows installation, and decided that's where it should be installed too. Now, what I would like to do - and I would really like to do it this way - is reformat both the disks, wiping out everything that's on both of them; before running another installation.
BTW: the old data drive is still NTFS, and I don't want installations own both disks - reformatting and starting fresh seems nice and clean, if not entirely necessary.
